     If needed, one can force a call to an extension by casting the receiver to a static type: `(d as Foo).bar()`
 - Augmented assignments on dynamic receivers (e.g. `dyn += foo`) are resolved to `plusAssign()` function, not `plus`, for generality:
   this permits calling them on vals (e.g. those holding collection-like objects)
