Grumble grumble grumble....
Okay, I'm sorry for being difficult. I really couldn't find the answer
in the Perl documentation.
I understand the second set of curly braces. I also, somewhat,
understand that the -> replaces the % (i.e. - reference dereferencing).
What I'm not so clear is what the first set of curly braces do (what do
you mean by "casting" - casting to what? How is that decided?). I'm also
not clear on why the surrounding round brackets are needed. I understand
they are so this will be a list context, but I don't understand why it's
needed once I put a @ to dereference the array.
Thanks,
Shachar
foreach my $elem (@{$ref->{a}})
