Just for reference for anyone interested, in my own case I've worked around
it like this:
class Foo(char[] str)
{
static const char[] StringOf = "Foo!("~str.stringof~")";
}
static assert(Foo!("a").StringOf == `Foo!("a")`);
Similar workarounds can be done for other template signatures, like a
custom-made function for enums, or a "static if(StringOf exists) use
StringOf else use stringof" for general T types.
