Ah.  Well, YMMV.  If you have repeated calls to functions (not class 
methods, these are not optimized), it can be quite significant - you have 
an extra opcode that includes some stack manipulation, string duplication 
and strtolower of the function name, and slower pass_param opcodes.  I 
never actually benchmarked it, but it can be quite significant.
