Mostly I am not leaning at all... I agree that () can be cluttering, and
many would say that
while (my $line = <>) {
}
or
foreach my $element (@some_list) {
}
Is silly since Perl is going to provide me with $_ anyways, but 30 lines
later, after $_ may or may not have been mangled by however many
functions and regexes, etc. I like to have $line to hold onto, rather
than relying on the $_ joker in a house of cards, but I have had to read
*a lot* of *bad* Perl written by people who didn't know better.
Essentially my jest goes back to Perl giving one ample amount of rope to
string somebody up with, and while it is sometimes yourself, more often
it is your poor maintainer coming behind you. Besides I like variables,
so I at least like to show them the professional courtesy of calling
them by name when I yell at them for doing something they were told
rather than what I wanted. Of course grep/map not withstanding...
So how does this relate, well often the same camp that complain about
having to type an extra character here or there are also the camp that
make *overly* judicious use of $_ and his cousins...
Maybe I just don't get to write enough one liners....
