I support using $_, but you should perhaps implement a standard/guideline in the form of 'Localize $_ in all user created subs', as something like the following:
sub foo{my $blah=shift; $_=substr $blah,0,1; /foo/;}

Which looks fairly innocuous in the use of $_ to avoid more temporary vars (It's not an extremely good example, but it serves), but then you do something likemap{foo($_->[0]);$_;} which can return wildly different results then you expected, and lead to many.. interesting.. bugs.
