So do I need to be able to "call a function as if it were a procedure", or is there a stark difference between the two types of callable?
Well, Pascal makes a stark distinction between them -- it's a compile-time error to call a procedure as though it were a function or vice versa in Pascal -- and it didn't seem to cause any great problems. So it's at least possible to write useful code under such circumstances, and it might even help to catch certain classes of errors. But the ability to ignore return values can be useful as well. Most languages since have decided not to make the distinction, and don't seem to have suffered noticeably as a result. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
