Every style guide should have a rule that says "break these rules if you
consider it sensible to do so, but be prepared to justify your
decision", or something to that effect. Especially so if the rules are
draconian. Otherwise you'll end up with stuff like
# Remove the first space from all thingies
use Readonly;
use Regexp::Autoflags;
Readonly my $SPACE => q{ }; # Single space
Readonly my $EMPTY_STR => q{}; # Empty string
foreach my $thingy (@thingies) {
$thingy =~ s{ $SPACE }
{ $EMPTY_STR }o;
}
instead of
s/ // for @thingies;
or something.
Astute readers may recognise the rules I am attempting to use.
(Incorrectly, in all probability.) But I am really trying to make a
general point rather than pick holes in any particular set of rules.
