You might find Data::Dumper helpful. Try adding the following to the end of your script:

use Data::Dumper;    # you could put this at start of script

print Dumper(\@all_matches);

This will print your data structure in a fairly easy to understand format (see the documentation for details). It might help you to find and understand what is undefined.
