Re: more fun with references and hashes

To my knowledge, you cannot return a hash, you have to return a reference from your sub, so return \%new_hash, and in your main code:

my $ref = duplicate_probe_signals(\%clocks);
my %new_hash = %$ref;

It is possible to return a hash... `#!perl -w use strict; use Data::Dumper; sub test { my %hash = ( a => 1, b => 2, c => 3, ); return %hash; } my %got_this = &test; print Dumper( \%got_this );` [download] The hash returned is simply a list that happens to have an even number of values (and unique values in the key positions 0,2,4,6,8etc.).
