Sorry James, you got a second copy. I meant to reply
to the group.
James,
thank you, thank you!
Can you explain this syntax then, that is used with
foreach loops?
foreach my $i (keys %{$x}) { ... }
Why don't we use foreach my $i (keys $$x){... }?
> > What is the name for this syntax: "(keys %{$x})"?
Thanks,
siegfried
