I haven't decided on that yet. I need to implement first the type 
marshalling interface between Red and Red/System and see then, what 
is the best option.

Interesting info, Brian. However, I wonder what rebcode! would be 
needed for when you can inline Red/System

The advantage to rebcode isn't that it's fast, it's that its semantic 
model is similar to assembler. That makes it useful for a lot of 
interesting problems. Also, there might be times when you don't want 
to allow Red/System to be inlined - it's basically the same as unsafe 
code in C#, with the same security characteristics.

Yes, but RebCode is aimed at an interpreter. In Red we can make any 
safe dialect we want that compiles to Red and/or Red/System

If Red's compiler is implemented well, there shouldn't be any reason 
that it would be slower than the equivalent Red/System code. Red/System 
is just less safe.

In Red, there might be an advantage to making a compiled rebcode 
equivalent (but without the stability and security bugs). Unlike 
REBOL (ignoring the debate), rebcode is inherently compilable. It 
wasn't designed to be interpreted the way REBOL was. It just had 
a fast interpreter implementation, which has been adapted to other 
dialects in R3.

Right, found it, the DO-COMMANDS function. That is what implements 
the rebcode interpreter model. And it's another reason to have a 
command! type.

Sure, but Red and Red/System are also inherently compilable. I think 
there's very little advantage left in a virtual assembly dialect

Inherently compilable

 alone still leaves open a wide range of design possibilities. "Redcode" 
 could still explore design spaces opened up by a quite reduced source 
 language.

I guess the intermediate format in Red/System 2 will get you that

Yes, possibly.

Inline that, and presto: RedCode

BrianH: is the command! dispatch interface the same as DELECT?

DELECT takes a dialect that prepares the commands

Doc, regarding decimal!, do you mean the implementation will be different, 
or are you planning to use float! or real! as the datatype name?

The latter. I would like to keep decimal! name for a new BCD datatype.

I want to compliment you on the speed of development of Red! It is 
truly amazing. Keep up the good work.
Is this news also worth mentioning on the red-lang.org website?

Thanks Arnold. Not yet, I will make a 0.3.1 release for that, but 
it needs a few more days to stabilize.

FYI, I have started working on EXIT and RETURN implementation. It 
will probably take a day to design and implement them correctly. 
In the meantime, feel free to push issues with Red functions on the 
bugtracker.

Haven't read commints, so sorry if already answered - will there 
be a FUNCT equivalent, allowing to use local words only?

FUNCTION. It's mentioned here: https://github.com/dockimbel/Red/commit/cc5c8dcb839572bb25559f964ed7d30419cb5a31

Thanks Doc. I support the idea of decimal! as the BCD type.

Doc, I can see Rudolf being pretty active with testing Red, Red/System? 
Nice, I thought we have lost him when R3 went into a non-development 
mode ....

He showed up again shorter after Red first alpha release. He's working 
on updating the BNF grammar of Red/System to add namespaces.

No gob! Does this mean no GUI or just gui done in different way?

There are GTK+ and SDL bindings. There will be bindings to native 
GUIs in the future (I consider GTK to be the most native binding 
for Linux and BSD systems)

They're for Red/System for now, not connected to Red yet

Does this mean no GUI or just gui done in different way?

 See all the presentation slides for Red, a native GUI system will 
 be provided. Also a web server with a new web framework will be part 
 of Red stack, so modern style web apps will be supported.


The GUI will probably be done in different way than R3 underneath, 
maybe a gob!-like datatype will be a good match, but such implementation 
detail is not known until implementation starts. Also, it is possible 
to extract R3 GUI code, wrap it in a shared library and plug it in 
Red (but I won't be the one doing that and maintaining such wrapper).

As Kaj underlined, GTK+ will most probably be the native target for 
Linux.

I've finally been able to write a Red version of Fibonacci numbers. 
It executes twice as fast as R3

Red/System is roughly hundred times faster

Is the Red version pure Red? Why exactly is it faster than R3?

It's compiled

parameter: 35

fibonacci: func [
	n		[integer!]
	/local	a
][
	either n < 2 [
		n
	][
		a: fibonacci n - 1
		a + fibonacci n - 2
	]
]

prin "Fibonacci "
prin parameter
prin ": "
print fibonacci parameter

Functions in red are not compiled yet, right ?

Wrong.

Functions are compiled  in Red.

I talk about Red not Red/system

Yes, Peter i right

Me too!

is

I think you're both wrong ;-)

Red is a compiler, as simple as that

Well I'm usually worng :-)

You're talking 	about Red/system not Red

Red is evaluated

No, we've been publishing that fact for almost two years now. I don't 
know what else we can do

like Rebol

No, it is compiled like C.
