Your 'throws' template seems good. Should create std.testing and 
include it there.

Also, perhaps it'd work to use a double-template for this:

	template throws(Exceptions...) {
		void throws(TCallable, string filename=__FILE__, int line=__LINE__)
			(lazy TCallable callable) {
			...
		}
	}

I know this trick was working in D1, but I'm not sure if it wasn't 
broken in D2.
