To me, this is a big reason for Typedef being of little use. It's just
so easy to use struct + alias this to achieve what you want (and to do
so without tricky issues or hacks like counters or whatnot, plus you get
to control exactly how it should behave without bothering with template
parameters -- you can even do things like overload operators / methods,
that Typedef can't do), that I find myself wondering what Typedef is
actually good for, if anything!
