I guess you didn't have time to check out the video. What I mean
is, the solution is to change the signature of "createWindow":
alias Width = Typedef!(int, int.init, "Width");
alias Height = Typedef!(int, int.init, "Height");
void createWindow(string title, Width width, Height height);
This solves the issue of accidentally passing the wrong thing
with i"Window $id", and also prevents non-interpolation-related
accidental usage, like mixing up the width and height.

I agree with this 100%, except I think it's a point against DIP
1036 and in favor of the other proposals. :)
We already have ways to put stuff in the middle of strings. The
reason we want string interpolation is to make the syntax for it
less ugly. So, it *should* be "just syntax sugar." Anything
beyond that is bloat.
