Two reaons: strict and the GetOptions() hash. The latter was actually what gave me the idea in the first place. The script started out having a series of
{ do_this(\%options, $table), last if $action eq 'this'; do_that(\%options, $table), last if $action eq 'that'; # ... die "Usage here\n"; }
Look a bit harder and you'll see method calls in disguise.. With this new approach, all I have to do is write sub _more {} and the script will automatically understand the "more" option - and it works with strict too. (Plus can $execute $_action looks much prettier than defined &$_action IMHO :-))
