1. while (<>) { ... } or while (my $line = <>) { ... }
   The former, unless the code is complex enough warrant explicit readability.
2. -w or use warnings;
   The former, although i am slowly gravitating to the latter.
3. sub CONSTANT () { ... } or use constant CONSTANT => ...;
   The latter, it just looks nicer to me.
4. my ($foo, $bar) = @_; or my $foo = shift; my $bar = shift;
   The former.
5. for (@array) { ... } or foreach (@array) { ... }
   The former, since they are really the same (barring readability issues), why type more?
6. print 'foo'; or print('foo');
   The former, unless the print becomes complex enough that parens are necessary, which is not that often for me.
7. 'simple string'; or "simple string"
   The former, i try to only use double quotes when i need something interpolated.
8. glob '*' or <*>
   The former, until it bites me and i resort the latter. :D
9. readline *FOO or <FOO>
   The former, until it bites me and i resort the latter ;)
10. for (keys %foo) { $_ and $foo{$_} } or while (my ($key, $value) = each %foo) { $key and $value }?
    Depends. If the value is more than a simple scalar or i find my self using the values a lot then i will strongly consider the latter.

Here is one i have been contemplating lately: print "$foo\n"; or print $foo,$/; :)

Agreed. Why risk a careless update to the string that contains a $ or @ and the associated problems when you intended to print out the literal string?
