They shouldn't always be possible. It is a laxity in the grammar that
needlessly causes context dependencies. And, in this case, rejection of a
perfectly valid language construct.

Even if the context dependency is not removed, the interpretation of 'classname
(variablename)' as a constructor call should be considered by the parser.
