in reply to Elegant way to return true or nothing from a subroutine?

How about: 
sub foo {
    shift->{some_obj}->some_method && 1 || return
}

Personally I think your attachment to requiring that all your true values be 1 is vaguely silly. A better solution would seem to be: 
sub foo {
    shift->{some_obj}->some_method || return
}

Wah! Guess who's been programming in ruby recently. I initially wrote those as sub foo; ...; end
