Foobar a = doesThisExistInPhobos!Foobar("foo");

I'm not finding anything like it in the docs, but I'm wondering if I
just missed it somewhere.


import std.conv : to;
Foobar a = "foo".to!Foobar;

I'm sure it'd be easy enough to write, but does phobos have a simple way 
to convert the name of an enum member from a runtime string to the enum 
type?

Foobar a = doesThisExistInPhobos!Foobar("foo");
