Re: Dereferencing a Hash of Arrays

Your problem is that the values in hashes can only be scalars in Perl. However references are scalars, so you can use references to arrays:

my %alphabet = (
    a => \@atags,
    b => \@btags,
);

say for values %alphabet;

Hi Philipbailey, I tried that earlier but `man perlref` told me I could abbreviate that as `my alphabet = \(...`. Are they not the same?	[reply] [d/l] [select]
