Nope. I couldn't make sense of the mixin. (Also, this only works 
because of a compiler bug that I didn't know about.)

WAT?! Why is concatenating a function pointer with a char string 
not an error, even in @system code?

unittest {
     // This passes!
     assert(is(typeof(cast(typeof({})) 91) == void function() pure 
@safe nothrow @nogc));
     assert((cast(typeof({})) 91) ~ "" == "[");
}

I filed a DMD issue:
