++ That is very nice. I didn't realise that you could use my and \() like that. Learn something new every day!

The only pain is that you have to remember to do:

my @A = \my %Foo;

not

my @A = \my (%Foo);

... which could lead to some nasty buggettes if you're not careful.

    Odd. I didn't even notice. I'm not sure I understand - I shuffled parens around but there's no difference. This is funny and sort of embarrassing.. what am I missing?

    Makeshifts last the longest.

      A single hash is a special case with \(). From perlref.

      As a special case, "\(@foo)" returns a list of refer- ences to the contents of @foo, not a reference to @foo itself. Likewise for %foo, except that the key refer- ences are to copies (since the keys are just strings rather than full-fledged scalars).

      Annoying eh?

        Wow, ya learn something new every day. Yes, annoying indeed. Ugh.
