Very interesting.

I started with the Mastering Perl Algorithms code (I left it in a subroutine), and abandoned it for the ternary when the ternary was faster. Of course, the subroutine entry was the main speed bottleneck.

This is fascinating. In the if/then/else results, we pay a considerably higher cost for the "constant item," "scalar variable" and "scalar assignment" operations. I wonder why that is so... Even the numeric comparison is more expensive in if/then/else than book max.

Also, your grep benchmarked slower than if/then/else. I saw the opposite. Would you post your complete code, to let me compare?

Thanks, you've made a fantastic post!
