Programming Tips - Any obscure operators in perl 5?

Date: 2011aug3 Source: Talk by Damian Conway Language: Perl Q. Any obscure operators in perl 5? A. Did you know about the "tends to" operator in Perl? Like Calculus limits. Looks like --> For example:
$count = 10; while ($count --> 0) { print "$count\n"; }
This is a joke. Its really the familiar decrement (--) and greater than (>) squished together :) ie:
$count = 10; while ($count-- > 0) { print "$count\n"; }
Perl will run both these examples the same. Apparently it works in C and other languages. Impress your friends with the mysterious "tends to" operator.
