Description Dylan Knutson 2013-05-17 23:39:09 UTC 
Instances of an enum of type string can't be passed into a switch or final switch:

----
enum Test : string {
	Foo = "Foo",
}

Test a = Test.Foo;
switch(a) {
	case Test.Foo: break;
}
----

even though a string is a valid type to pass into a (final) switch. 

Compiler error: 
Error: 'a' must be of integral or string type, it is a Test

but obviously the underlying type of 'a' is string.

Sorry; I forgot to include compiler info.

Even though the pull didn't test this, the -g switch seems to work too. (in my pull this didn't work). It may be a good idea to add -g in the PERMUTE_ARGS section though, to avoid regressions.
