Yeah. But the need for wantarray is, in my experience, rare indeed. Almost always, I'm happy to let the normal context handling do its thing. For example:

    # let array handle context.
    # list of items in list context, count of items in scalar.
    sub find_things {
       my( $storage, $criteria ) = @_;
       my @things = $storage->lookup( $criteria );
       @things
    }

    # let grep handle context.
    # list of items in list context, count of items in scalar.
    sub matching_things {
       my( $storage, $pat ) = @_;
       grep /$pat/, $storage->things()
    }

That's not to say that wantarray is never useful. For example, if building a result list is expensive, you can use wantarray to avoid that cost in scalar context.

    # list of items in list context, first item in scalar.
    sub matching_things {
       my( $input_iter, $pat ) = @_;
       my @things;
       while ( <$input_iter> ) {
           /$pat/ or next;
           wantarray or return $_;
           push @things, $_;
       }
       @things
    }
