Re: How do I rewrite this foreach() loop as a map{} ?

foreach (sort { $a <=> $b } keys %hash) { push @c, \@{$hash{$_}}; }

maybe something like:

@c = map { 
  \@{ $hash{$_} }
} (sort { $a <=> $b } keys %hash);

Note that this is untested and will replace @c with the result of the map. You could append to the @c array like so:

push @c, map { 
  \@{ $hash{$_} }
} (sort { $a <=> $b } keys %hash);
