I do not even understand the topic nor the syntax `perl -e "my $c = 10; print qq!$c\n! while $c --> 0;"` [download] but I see that also `perl -e "my $c = 10; print qq!$c\n! while $c ++> 0 && $c < 100;"` [download] runs fine.. BUT what a notation is this --> or ++> ? there are no rules, there are no thumbs..	[reply] [d/l] [select]

--> is the autodecrement followed by a greater than. It looks like the arrow operator used in various languages, but `while $c --> 0`is really just `while ($c--) > 0`	[reply] [d/l] [select]
