[REBOL] Re: Parse versus Regular Expressions

From: greggirwin:mindspring at: 4-Apr-2003 10:15

Hi Joel, << 2) It totally breaks normal usage that "or" is symmetrical, even though we read the | as "or". >> It's like the ANY function, so I don't know that I'd say it "totally breaks" normal usage. Isn't OR often optimized to work this way; i.e. shortcut evaluation? I think the most important thing, barring actual "bugs" in PARSE's design is documenting how these things work so grammars can be designed correctly (e.g. longest match first; greedy grammars? :). -- Gregg
