A question of Style, was: SPUG: Sort an array question

[Geoffrey & Kristin Grosenbach]

This is a fascinating benchmark...I had a co-worker tell me that the 
c-style loop was faster because Perl didn't have to keep track of the 
array on it's own, but he didn't have any code to back it up. I'll have 
to show him this one.

And since we're sort of on this topic, does anyone have any 
recommendations for convincing co-workers that writing readable code is 
actually better for the company's bottom line?
    I can enforce coding standards for the coders I manage, but I had a 
conversation last week with another who said "It only takes me an extra 
one or two hours a week to maintain our current [obfuscated] codebase, 
and a rewrite wouldn't gain us any more than one or two hours a week, so 
it's not really worth it financially."
