Howdy all, I've recently packaged 'enum' in PyPI. In its description, I make the claim that it creates "immutable" enumeration objects, and that the enumeration values are "constant" values.
This raises questions. Is there any difference between a Python immutable value, and a constant? I suppose "constant" also implies that the *name* binds unchangeably to a particular value. Is that meaningful? How does one actually ensure an object is immutable? Is it a matter of overriding a bunch of methods, or is ther a neater way? Is it bad style to make a user-defined class that creates immutable objects? Why? In the case of 'enum', can anyone argue for or against an enumerated type being immutable? Its values being constant? -- \ "The best ad-libs are rehearsed." -- Graham Kennedy | `\ | _o__) | Ben Finney -- http://mail.python.org/mailman/listinfo/python-list
