You mean by behavior or error message should be the same as for
builtin? I think implicit assignment operator should provide the same
behavior.

No, of course not. Only assignment operators from the class and
parents. Yes that will require filtering the list. Another idea is to
print "incompatible type" message when there is only one assignment
operator available. That will require filtering that list as well.

New patch is attached. I also added some test cases for compound
assignment operator.

Thanks,
