Re: Vectors as functions

Funny you should mention that.....

I wrote the Rebol 1.0 interpreter.  (but left the company right afterwards)

Rebol is *extremely* difficult to compile in any meaningful sense.
Since the parse tree can change dynamically at runtime, there is
a combinatoric explosion of code paths.  You can constrain
things a bit by allowing the user to declare procedure arity, though.
