class | ASTStmtReader |
A reference to a name which we were able to look up during parsing but could not resolve to a specific declaration.
This arises in several ways:
These never include UnresolvedUsingValueDecls, which are always class members and therefore appear only in UnresolvedMemberLookupExprs.
