Though be aware that since EnumMembers results in a TypeTuple,

Normally, that doesn't matter, but if you try and do fancier
stuff, the fact that the foreach is executed at compile time
could affect what you're doing, and if want your function to be
small (e.g. inlining), then that would cause problems.
But that problem goes away if you turn it into a small array
right? (And pass the array to the foreach to cycle over) So
throwing that idea out there you get...
foo[] array;
foreach(m; std.traits.EnumMembers!foo)
array ~= m;
foreach(m; array) {
//not compiler-time expansion like above
}
