As far as $_, I think that the problem of the many uses can be overcome by simply doing 

{
    local $_;
    # stuff...
}

.

I haven't seen this do anything too weird, and it provides a good way to overwrite $_ temporarily. It sort of reminds me of elisp's (save-excursion ...) Anyway, here's my answers to the questionnaire -- favorites are first.
(Least) Favorite Perl Instructionlocal; resetSee above. Why reset? Too dangerous, especially when you've got tons of single-char vars.
(Least) Favorite Looping Mechanism{}; forNaked blocks give you more flexibility. for just seems useless to me.
(Least) Favorite ModuleData::Dumper;Dump those objects! No least favorite -- I sort of like them all.
(Least) Favorite Special Var$_; $]$_ is so useful. $] is not.
Favorite Var TypetypeglobVery obfuscatable.
(Least) Favorite Command Line Switch-e; -U-e allows me to do one-liners. -U does unsafe things.
Favorite Pragmause strict; no strict "refs";Good for bugcatching, except when I want to use symbolic references.
Favorite Regexp {Modifier,Metachar}i; \QYes to i! Too much work to manually decapitalize all the time. \Q useful for when arbitrary data comes in which you need to match.
Favorite Descriptive Var Name%zNot very descriptive, but I like it nonetheless.
Favorite HERE doc delimiterprint;Or some other command...
Favorite FilehandleFOOShould be obvious why...
