What about:

	auto noThrow(T,U...)(scope T function(U) t) nothrow {
		return (cast(T function(U) nothrow)t)();
	}

	auto noThrow(T,U...)(scope T delegate(U) t) nothrow {
		return (cast(T delegate(U) nothrow)t)();
	}

?

(I've no idea if this actually works, but it does allow you to wrap
almost _any_ function.)
