I used the following lines to make it work for Unknown and I 
think even Voldemort types.
```d
static foreach(att; allFieldTypes){
			//pragma(msg, "alias %s =att;\n".format(att.stringof));
			mixin("alias %s = att;\n".format(att.stringof));
		}
```
But I don't know how to do this (in a general) for UDAs, since 
they can be values instead of types too, i.e. @UDA(Voldemort!2(3))
