Ok, but CastExpression (15.16) is defined as:

CastExpression:
        ( PrimitiveType Dims opt ) UnaryExpression
        ( ReferenceType ) UnaryExpressionNotPlusMinus

... so "( ReferenceType )" has to be followed by UnaryExpressionNotPlusMinus to be recognised as CastExpression, whereas "parenthesized function call" (I think) can never be followed by anything that looks like UnaryExpressionNotPlusMinus.

It would be best to find a full contra-example...
