in reply to Ways of quoting

Hi

IMHO the only purpose of assigning a package's name to a scalar is to handle it later in a referential or symbolic way.

For instance $x->can("function") will return a code ref if "function" exists in the package.

So the benefit of writing $x = anything_could_go_here:: over $x = 'anything_could_go_here' is only catching the error when misspelling the package's name.

(you already demonstrated this after activating warnings )

I'd strongly discourage using this as golfing hack to avoid single quotes around normal strings.

    Yeah, clearly just using it as a sneaky way of quoting doesn't work.

    Having said this, one thing I've done in the past is something like this:

    use Const::Fast;
use A::Really::Long::Class::Name::To::Type;
const my $CLASS => 'A::Really::Long::Class::Name::To::Type';

$CLASS->do_something;
$CLASS->do_something_else;
$CLASS->yet_another_thing;
# 
# and a bunch more of these
#

    In that circumstance, seems to me that

    const my $CLASS => A::Really::Long::Class::Name::To::Type::;

    [download]

    might actually be preferable, in that it gives you that check against the package name.

    All I can say is I've been using perl since the '90s and I still have so much I don't know.
