in reply to Complex if/else or case logic

If it is all constants:

my %actions = ( 'sender a' => { 'some text' => { 'some other text' => 'type 1', 'some other other text' => 'type 2', }, 'some other subject' => { ... }, }, 'sender b' => { ... }, ); sub action { my( $sender, $subject, $body ) = @_; my $rv = $action{$sender} // return 'unknown sender'; $rv = $rv->{$subject} // return 'unknown subject'; $rv = $rv->{$body} // return 'unknown body'; return $rv; }

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
