It seems the concensus is that empty enums should be allowed for consistancy, and to support the loop that doesn't. I thought I'd find some data points in other languages as a guide:
* C - builtin, empty enumerations not allowed * C++ - builtin, empty enumerations allowed. C++ doesn't have iteration over a enumeration, except as a side-effect of direct translation from elements to integerts (and then, only for a sequentially assigned enumeration). An enumeration is a type, so it can be thrown (raised) as an exception - http://oopweb.com/CPP/Documents/CPPAnnotations/Volume/cplusplus16.html#EMPTYENUM * Java - builtin, empty enumerations allowed previously to 1.5, but maybe not after - http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5081785 * OCaml - library, empty enumerations allowed as a consequence of being able to add and remove enumeration elememts: http://ocaml-lib.sourceforge.net/doc/Enum.html I realize this is a strange and short list, but it's all I can do with 5 min of Google and a little testing. -- http://mail.python.org/mailman/listinfo/python-list
