I've looked at this for a few days but still can't see 'why'
I get what I do.
Why do @arrays and @seconds not have the same number of elements?
Thanks,
Mike
{ my %HoAoA = (
a => [ [ qw / aa1 aa2 / ], [ qw / ab1 ab2 / ] ],
b => [ [ qw / ba1 ba2 / ], [ qw / bb1 bb2 / ], [ qw / bc1 bc2 / ] ],
);
# this gets refs to all arrays
my @arrays = map { @{ $HoAoA{$_} } [ 0..$#{ $HoAoA{$_} } ] } keys %HoAoA ;
# this only gets the second entry from the last array of each hash entry
my @seconds = map { @{ $HoAoA{$_} } [ 0..$#{ $HoAoA{$_} } ]->[1] }
keys %HoAoA ;
print "\...@arrays = @arrays\n";
print "\...@seconds = @seconds\n";
}
