Class name should be ImmutableDict

[cool-RR]

I think that the name of the class should be ImmutableDict rather than immutabledict. Python's standard library uses lower-case names like that, but it's standard for third-party packages to use camel-case for class names.

I agree, I keeped it like this for now to have a naming scheme similar in casing to frozendict. I may change it for a further release to have a more standard naming schema :)

It doesn't have to in this case. Look at namedtuple

[ArneBachmannDLR]

Same as frozenset, tuple, dict.

Yeah I think it's good to do like namedtuple and keep something similar to dict, frozenset, and tuple, especially since it was already the case in frozendict, so I will close this issue.
