What is the practical purpose of such a thing?

The two cases I can think of are:
1. To define a set of supported handlers which can be passed in
as a parameter to a call. Rather than writing a switch in your
method that calls the correct function, based on the supported
values in the enum, you build the handlers right into the enum.
It pulls your code into one.
2. If you have a quick and easy method for serializing an enum -
for example, converting the name to a string and back - then you
can write can write code that deserializes and calls a function
in a single line.
But mostly, I was just curious.
