Hey, neat bug. Somebody posted a program that can be made 2.5 *times* 
slower by renaming some functions. (!!)

The glitch, it turns out, is because the compiler automatically inserts 
an error handler into the function, and it prints out the function's 
name. Having a sufficiently long function name tips the function's "cost 
estimate" over the maximum limit for being inlined. So the function 
doesn't get inlined, and consequently runs much slower.

Heh. Starting to understand why building a production compiler is so 
damned hard... ;-)
