Oh, and to throw a monkey wrench in here, the value is a string, not
an integer. So I can't use std.conv.to to verify the enum is valid
(plus, then I'm running a switch twice).
Any ideas on better ways to handle this?

Why not just:
try {
MyEnum value = input.to!MyEnum;
} catch (Exception e) {
stderr.writeln("Invalid input");
}
Yeah, that was a possibility I listed. Of course `to` is going to do a
switch, which means then after I validate the value is valid, I then
have to do a final switch to process it. I'd prefer to do it both in one
switch.
