I'm not sure whether I like it or not, but I note that Python allows this:
every enum member must have a value, which can be of any type; if two members
are given the same value, the later defined one is considered an alias of the
first. There is a method to select an instance by value, which will always
return the first member with that value, not the alias. The examples also
include lots of ways of using the value with overloaded operators etc.
