Surely you don't mean that only a "static method" can be called in a
consequence?!

Also, using 5.3.0 and 5.4.0.Beta2,.I had no problems with a consequence
    modify( $ms ){ add( "three", "four" ) }
    insert( new MySet( "x", "y" ) );
where both method add and constructor MySet have the signature (String...
strings)

But - as in many other situations - using
   dialect "mvel"
is to be avoided.
