I know that it this is not hard to write by myself, but in order to avoid reinventing the wheel: Does someone know a CPAN utility module, which has a function to create a subset of a hash, so that the newly created hash contains only those keys of the original hash which match a certain regexp? Kind of 

my %new_hash=();
grep { 
  $_ =~ $my_regexp && $new_hash{$_}=$original_hash($_) 
} keys %original_hash;
