Summary: Create context-sensitive return values
Usually, when you need to create a subroutine that returns different values
in different contexts (list, scalar, or void), you write something like:

    sub get_server_status {
        my ($server_ID) = @_;

        
        my %server_data = _ascertain_server_status($server_ID);

        
        
        if (wantarray()) {
            return @server_data{ qw(name uptime load users) };
        }
        if (defined wantarray()) {
            return $server_data{load};
        }
        if (!defined wantarray()) {
            carp 'Useless use of get_server_status() in void context';
            return;
        }
        else {
            croak q{Bad context! No biscuit!};
        }
    }

That works okay, but the code could certainly be more readable. In its
simplest usage, this module makes that code more readable by providing
three subroutines--'LIST()', 'SCALAR()', 'VOID()'--that are true only when
the current subroutine is called in the corresponding context:

    use Contextual::Return;

    sub get_server_status {
        my ($server_ID) = @_;

        
        my %server_data = _ascertain_server_status($server_ID);

        
        
        if (LIST)   { return @server_data{ qw(name uptime load users) } }
        if (SCALAR) { return $server_data{load}                         }
        if (VOID)   { print "$server_data{load}\n"                      }
        else        { croak q{Bad context! No biscuit!}                 }
    }
