Enum support?

[Y Bayk]

Are enums supported?

Would be nice if enums are mapped to Strings (similarly to how interfaces are mapped to js functions via @ExportClosure):

Java:

void foo(MyEnum myEnum);

MyEnum bar();

JS:

void foo(String myEnum);

String bar();

Also ideally, each exported Enum needs to be auto-documented with a set of its available values (perhaps in a method documentation)
