in reply to Idiomatic optimizations

Most of the optimizations listed can be found in the "Other Oddments" chapter of the Camel in the section "Efficiency". But one of my favorites (also in the Camel, but paraphrased using $x/$y/$z instead of $a/$b/$c):
Use $foo = $x || $y || $z; This is much faster (and shorter to say) +than: if ($x) { $foo = $x; } elsif ($y) { $foo = $y; } elsif ($z) { $foo = $z; }

[choroba]: Low-end is defined as the Perl that generates millions of income
[choroba]: sorry, that's high-end, of coursse

[choroba]: I want to present the most bizzare bugs and misfeatures I met when working for a large financial institution
[choroba]: I already gave a similar talk to my friends in a pub and at an internal conference at work and people liked it, so maybe...
[choroba]: LanX: That's the heritage, I can't do anything else
[RonW]: Sounds like some system my employer has "It does exactly what we need it to do and can't afford to risk anything we can't prove is 100% compatible"
[marto]: choroba sounds interesting
[RonW]: james28909 Why not write a Perl program to do the task?
