This method is used both when an enum class is given a value to match to an enumeration member (i.e. Color(3)) and for the functional API (i.e. Color = Enum('Color', names='red green blue')). When used for the functional API: `module`, if set, will be stored in the new class' __module__ attribute; `type`, if set, will be mixed in as the first base class. Note: if `module` is not set this routine will attempt to discover the calling module by walking the frame stack; if this is unsuccessful the resulting class will not be pickleable.

Those overrides are in place so that code detecting stdlib enums will also detect aenum enums. If a buggy __getattribute__, __instancecheck__, or __subclasscheck__ is defined on a custom EnumMeta then RecursionErrors can result; using this function after importing aenum will solve that problem, but the better solution is to fix the buggy method.
