Hello!
15.15 says:
The following production from 15.16 is shown here for convenience:
CastExpression:
( PrimitiveType ) UnaryExpression
( ReferenceType {AdditionalBound} ) UnaryExpressionNotPlusMinus
( ReferenceType {AdditionalBound} ) LambdaExpression #
Before it was clear that CastExpression is for completeness here, as
other operators are covered above. Now it's unclear why CastExpression
production is shown here for convenience, but switch expression is not
shown. Probably both should be shown or both removed.
With best regards,
Tagir Valeev.
