I agree with the notion that optimizing during development can be
counter productive. However, one can't always blame the compiler for
poorly optimized code. Function calls and array assignments are
notoriously difficult for a compiler to optimize. It often takes "a
priori" knowledge to know that a particular call or array access or
global reference is "safe". And while humans are terrific at
recognizing *new* patterns, machines aren't. They can only recognize
the patterns they've been trained to recognize.
