    ++ 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?

    I thought I remembered seeing it done something like that. I had tried my \(%Attr1,%Attr2,%Attr3). Thanks for the tip.
