I think you're talking byte code, and Tim's meaning source code. I think he's right; I would like to be able to write a perl6 script that says "don't make GC stall" and still have it work when I ran it on a perl6 implementation with a different sort of GC. [and if that GC never stalled, or at least didn't have a choice of speed vs compactness, it would just politely ignore my request because it was irrelevant] Nicholas Clark -- Even better than the real thing: http://nms-cgi.sourceforge.net/
