[REBOL] Ifs Re:(2)

From: lmecir:geocities at: 12-Oct-2000 8:23

Hi Joel, I am not glad, that I must disappoint you, but see the following example: a: 1 b: to paren! [to paren! [to paren! [to paren! [a: 0 - a]]]] ifs-for-dummies b [negative: ["Negative"] zero: ["Zero"] positive: ["Positive"]] == "Zero" I think, you should read Exception #5 for Word Evaluation of my Rebol/Core User's Guide Comments once again and hope, that this will be interesting even for others... Regards Ladislav P.S. My strong opinion is, that the best you can get is: signed-if: func [ {If positive do positive-block, zero do zero-block, negative do negative-block} [throw] condition [number! char! money! time!] positive-block [block!] zero-block [block!] negative-block [block!] ] [ either positive? condition [do positive-block] [ either negative? condition [do negative-block] [do zero-block] ] ] I am afraid, that Signed-if-for-dummies may become a victim of the GC bug and similar issues, when used recursively...
