Just for pedantic clarity, what C< $directive ne 'VAR' & 'LOOP' & 'IF' >
really gives is

    all( $directive ne 'VAR', $directive ne 'LOOP', $directive ne 'IF' )

In other words, the result of the expression is an all() Junction.
In boolean context this would indeed evaluate to false if $directive
has any of the values 'VAR', 'LOOP', or 'IF'.
