in reply to In Love With Double Quotes

I'm surprised that no one has mentioned my favorite reason for using single quotes instead of double quotes (in this discussion or the last): more whitespace. Whitespace is pretty, and ' takes half as many pixels as ". Witness:
my $foo = "fhwgads"; if ( $foo eq "fhwgads" ) { print "fh" . "wg" . "ads"; }
my $foo = 'fhwgads'; if ( $foo eq 'fhwgads' ) { print 'fh' . 'wg' . 'ads'; }
Doesn't the second example look *so* much better? Ahh, the beauty. Maybe I like whitespace a little too much?

    I can think of two reasons to use " by default instead of ':
    1. To disambiguate when using lots of `s, if your font isn't clear
    2. Easier to write text that uses contractions, e.g.
      open(my $fh, '/etc/motd') || die "Can't open /etc/motd: $!";
    YMMV.

    Do you also write:
    s.foo.bar.
    instead of
    s/foo/bar/
    or does your "more whitespace" rule only apply to string quotes?
