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.
