A lot of problem arise with current solution (loading them with lowpriority annotation + additional call checkers): - We errorneously treated ArrayList.stream as an existing method, while it's just a fake override from List - The same problem arises when creating a class delegating to List. Also the latter case is failing with codegen internal error (see issue KT-16171) The negative side of this solution is that instead of reporting meaningful diagnostic, there will be UNRESOLVED_REFERENCE. But it seems to be better than having strange problems like ones described above. #KT-16073 Fixed #KT-16171 Fixed
