It's not at all obscure:

 >>> class A(object):pass
...
 >>> type(A).__name__
'type'
 >>> A.foo = 1
 >>> A.foo
1

Look, Ma, I'm mutating a type!
No, son, you are just modifying it.

The properties you quote (comparison checks for identity, usable as a
dictionary key) don't imply at all that an object is immutable.
