Side-effects from aliased parameters are discouraged, since the order of the evaluation should not matter of an declarative evaluation of the argument vector. - extended regression test
- nsf.c: * add flags "-closure" and "-source" to "/cls/ info methods" (the cases for "/obj/ info methods" are already covered by "/obj/ info lookup methods") * extend regression test
