In the currently shown grammar yes. But the full grammar for the full DIL expression language has quite a few layers between "expression" and "cast_expression", and I don't think it would be correct to allow some of them here. So I would prefer to keep this as is at the moment, in anticipation of future changes. But I can make your suggested change if you feel strongly about it.
