Say something like this:

   my $results = [$source =~ m/$pattern/g];

Then the $results array has one element per capture by the pattern.

Make sure the whole pattern-match expression is in list context (such as my 
array value constructor provides) or otherwise it will just (in scalar context) 
return the count of matches.
