I'm not sure whether it is true, but the perldelta documents always
contain interesting and important-sounding performance improvements -
@_ using less memory, shift with no parameters being faster, in-place
sorting (including "reverse sort ..."), string appending getting much
faster. Given that these are the sorts of things that your average
large perl system will do a billion times a day it seems good to me
that they're always getting faster :-)
Anecdotally at $work we've used perl 5.8.8, perl 5.10.1, perl 5.12.3,
and perl 5.14.2 and I've not seen any drastic performance hit from any
of the upgrades.

Question seconded, anybody have actual figures to back up my wild theories?
