DslMarker

When applied to annotation class X specifies that X defines a DSL language

The general rule:

• an implicit receiver may belong to a DSL @X if marked with a corresponding DSL marker annotation
• two implicit receivers of the same DSL are not accessible in the same scope
• the closest one wins
• other available receivers are resolved as usual, but if the resulting resolved call binds to such a receiver, it's a compilation error

Marking rules: an implicit receiver is considered marked with @Ann if

• its type is marked, or
• its type's classifier is marked
• or any of its superclasses/superinterfaces
