For example, in C there is no notion of a string associated with an enum. But on the other hand there is a common expectation that it is possible to write a loop over all enumeration values, which is easy in C but is not clearly supported by your suggested syntax. I think it's necessary to first discuss the desired set of features. Until that is done, syntax can be a distraction.
