Though be aware that since EnumMembers results in a TypeTuple, the

be getting
bar(foo.first);

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
}
It's very useful tip, thank you too!
