Specifically, they must look like
Symbol.somethingorglobalThis.Symbol.something, and in the first case, that first identifier must refer exactly to the globalSymbolvalue (or not resolve at all, in which case it's the missing global by default). In the second,globalThismust exactly refer to the globalglobalThis.This should allow the common cases like
Symbol.iteratormembers and the like, without allowing complicated ones that might not be right like imports that refer to arbitrary maybe-symbol names.
