Ok, but don't ask me to use
  alias ALfloat = std.typecons.Typedef!(float, "yummyCookie23");
when it could be
  typedef ALfloat = float;

That was more of a pun on the original deprecation rationale:
  "typedef is not flexible enough to cover all use cases.
   This is better done with a library solution."
Frankly though it seems like templates are the improper tool
to create new unique symbols when at the same time we more or
less depend on templates only being instantiated once for the
same arguments.
