in reply to Ways of quoting

I have to admit, I hate the idea of the trailing ::.

If you're enumerating the ways to quote things in Perl, don't forget HERE docs:

<<HERE # Double quoted <<"HERE" # Double quoted, explicit. <<'HERE' # Single quoted, explicit. <<\HERE # Single quoted, uncommonly used. <<`HERE` # Same as qx or ``. <<~HERE # Double quoted, indented. <<~"HERE" # Double quoted, indented. <<~'HERE' # Single quoted, indented. <<~\HERE # Single quoted, indented, uncommonly used (I'll b +et you could grep all of CPAN and not find this). <<~`HERE` # Same as qx / ``, indented.

Which made me think, too bad we don't have:

<<~/HERE/x # Regexp object, indented, multi-line freeform (/ +x modifier).

    too bad we don't have: <<~/HERE/x
    my $re = qr/@{[<<'HERE']}/x; f . . HERE

    Close enough? ;-)

      Good enough for an upvote. I tend to shun the "@{[...]}" trick in real code, but this is a creative enough solution it made me smile.

        ... and commonly referred to as the baby cart.

        (As a speaker of en_GB that's not a term in our common usage. You are more likely to hear "buggy" or "pram". IMHO this makes the "baby cart" term even more preferable since it has a unique meaning for me - it's only the perl operator, regardless of context.)
