Perl Monks, please help. I want to generate all possible string combinations of N arrays. I am sure that there are several hundred ways that you guys could come up with to accomplish this. I only need one and it does not have to be efficient

A minimized version of my non-working solution is as follows:

my $string='echo {CAT,CAC}TGG{GTT,GTC,GTA,GTG}{CCT,CCC,CCA,CCG}'; my $combinations=`$string`; print $combinations;

The result that I want is

CATTGGGTTCCT CATTGGGTTCCC CATTGGGTTCCA CATTGGGTTCCG CATTGGGTCCCT CATTGGGTCCCC CATTGGGTCCCA CATTGGGTCCCG CATTGGGTACCT CATTGGGTACCC CATTGGGTACCA CATTGGGTACCG CATTGGGTGCCT CATTGGGTGCCC CATTGGGTGCCA CATTGGGTGCCG CACTGGGTTCCT CACTGGGTTCCC CACTGGGTTCCA CACTGGGTTCCG CACTGGGTCCCT CACTGGGTCCCC CACTGGGTCCCA CACTGGGTCCCG CACTGGGTACCT CACTGGGTACCC CACTGGGTACCA CACTGGGTACCG CACTGGGTGCCT CACTGGGTGCCC CACTGGGTGCCA CACTGGGTGCCG

The code returns {CAT,CAC}TGG{GTT,GTC,GTA,GTG}{CCT,CCC,CCA,CCG}
