I actually had them in my first draft. :)

	const(T)[] myVeryLongFunction(T)(const(T)[] arr,
	                                 int        x,
	                                 int        y,
	                                 int        z,
	                                 ExtraArgs  extraArgs)
		pure @safe nothrow
		if (is(T : int) &&
		    someOtherLongCriteria!T &&
		    yetMoreVeryLongCriteria!T)
	in {
		assert(x >= 0 && x < 5);
		assert(y >= 0 && y < 5);
		assert(z >= 0 && z < 5);
	}
	out(result)
	{
		assert(result[0] >= 0 && result[0] < 5);
		assert(result[1] >= 1 && result[1] < 6);
		assert(result[2] >= 2 && result[2] < 7);
	}
	body
	{
		...
	}

There. :)
