find/at  foo bar

== NaN

How can I check that a given value conforms to a typeset? E.g.,  
If I say "make typeset! [string! integer!]" how can I check that 
the number 17 conforms to that typeset?

I've written a recursive function to do it, but I wondered if there 
weren't some better way.

Never mind. I just issued "source any-string?" and got my answer: 
find typeset type? :value. Perfect.

On MIN/MAX with pairs, sorry I wasn't clear. I do NOT think it's 
a bug. I use that behavior myself, and seem to recall it being discussed 
long ago. It may not be what you expect initially, but I think it's 
the right design choice.

I just wanted to point it out in the context of pair comparisons.

how does one probe a map! ?

(probably an R3 question)

>> probe a
make map! [
    r 4
]
== make map! [
    r 4
]

>> foreach [key value] a [print key]
r
>> a/e: 5
== 5

>> foreach [key value] a [print key]
r
e

I just tried the most obvious and it worked.

>>foreach key a [print key]
works too.

how about this.. adding a variable as key in a map ie:
n: make map![]
b: 4398

n/b: "42" ; where b is 4398?

n/:b:

n/:b:

n/:b:

ah ;)

oups...

hmm... need a delimeter in the key.. 
n/8497:9823 ;err invalid time
n/9384-5842; err invalid date

n/123x345

... doesn't work...

you could use an integer to store the 2 values (but each one limited 
to 2^32)

>> a: 1234
== 1234
>> b: 345
== 345

>> key: b or shift a 32
== 5299989643609

or you can make a string with the 2 parts and the delimiter as a 
key, but it will cost more memory

>> m/("123-456"): 45
== 45

there's no end of keys .. could use zero as the delim i suppose

what would the mem cost be to use strings?

there's theory and reality, just make some tests using dp

dp? duck pond?

? dp

dp.. your acronym.. what does it mean?

? dp

it's a function of R3

is it possible to search the value of map! without looping?

well... take that memory problem aside for the moment , and go with 
string keys :)

wow

ouch, don't think so...
Actually maybe your real key is the value and not the key.

that is REALLY fast
1,000,000 GETs  in 1.387 seconds

can't use the value as the key.. it could be 1GB

no matter.. can't search by value in Redis either.. i have a work 
around

or create a second map! with reversed key-values

ok, you can't

I'm going to try more test.. but if this is accurate,  this would 
be nearly 10x faster than Redis

great.. there goes my weekend :(

thanks for your help

small detail that may be useful:

>> series? make map! []
== false

DP: :DELTA-PROFILE, meaning change in profile. It's R3's built-in 
profiler. R3 also has a built-in timer, DT: :DELTA-TIME.

happy to have helped  :-)

Terry, try FIND VALUES-OF map value, if you can afford to trade memory 
overhead for the loop.

can you return the key somehow?
