Description
If someone writes my $a or my $b (as could have be seen in trunk/Padre/lib/Padre/Document/Perl.pm until r8595) it should be pointed out that it is a bad practice to use either of those as they are special variables of sort().
Also any other use that is clearly not related to sort should be discouraged. I think and assignment to $a or $b should be also caught
but make sure to allow for external sort functions eg.
sub sort_by_num { $a <=> $b }
is a legitimate code.
Such practices should be probably caught in comments as well to avoid distributing bad examples?
