Static fields in Scala (SI-4581)
View gist:80f3141de8240f9629da

Proposal

Fields annotated @scala.static are generated as static fields. The this identifier is not in scope in static field initialization expressions.

A static field x defined in a class C can be referenced as scala.static[C].x. If the field is variable, it can be updated as scala.static[C].x = t.

A static field y defined in a singleton object C can be directly referenced as C.x and updated as C.x = t.
