They are static so they can't contain any mutable fields but 
surely they can contain methods? And especially they should be 
able to contain static methods!?

What prevents you from using UFCS with enum members or templates with 
enum itself? (not tested)

This is one solution, but it would still be useful as an 
organizational tool to be able to put those methods in the enum's 
own namespace.

If you want an enum type with methods, use a struct type that has methods.
Enums don't have to be integral types.
