Currently, the following fails to compile, with errors about expecting int instead of uint:

enum Animal {
  Cat = 0u,
  Dog = 1u
}

Is there any reason why this should be disallowed?

Allow uint discriminants and store them as such
1c3dc29 
Infers type of constants used as discriminants and ensures they are
integral, instead of forcing them to be a signed integer.

Also, stores discriminant values as uint instead of int interally and
deals with related fallout.
