Also, a good part of Perl's operators and functions will modify $_ in some way. Even if you don't use it, a function you call might, and it'll get changed. This leads to hard-to-debug code of the worst kind...

Reserve use of $_ to shell one-liners and map/grep blocks. The rest of the time assign your own variable.
