[REBOL] Re: Using Switch with Words ??
From: al:bri:xtra at: 1-Nov-2001 19:32
While it's easy to think that:
switch Value [
1 [print "one"]
2 [print "two"]
]
is just like C++'s (IIRC) :
switch value {
1: cout << "1"; break;
2: cout << "2"; break;
}
the power of Rebol is in the ability to manipulate itself. Notice that
'switch is a function, and it's second parameter is a block, so this works:
Switch-Block: [
1 [print "one"]
2 [print "two"]
]
switch Value Switch-Block
and then you can easily see how one can 'compose, 'load, 'do or 'reduce
Switch-Block to create interesting effects.
