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?
