PS: if there's any possibility that $selection could potentially contain an arrayref, then my solution might behave a little oddly; you could explicitly protect against arrayrefs:

sub is_arrayref (_) { ref(shift) eq 'ARRAY' } given ($selection) { when (is_arrayref) { die "unexpected!" } when ([wxID_YES]) { $self->Wx::LogStatus('You pressed: "Yes"' ) + } when ([wxID_NO]) { $self->Wx::LogStatus('You pressed: "No"' ) + } when ([wxID_CANCEL]) { $self->Wx::LogStatus('You pressed: "Cancel"') + } }

Of course, probably the code that generates $selection can never generate an arrayref, so you don't need to protect against that possibility.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'g
