Get over it, move on, and hope they fix the thousands of bugs left in DMD.

P.S.
use `alias`.

I've brought this up several times.
People just don't give a shit.

Sure they give a shit. :-) I think Andrei is currently looking into
ProxyOf for a new reference-counting type constructor.

There's a pull request being reviewed but nothing in Phobos yet.

Could someone please provide a link to the thread with the reasons for 
deprecating typedef?  There are too many threads with the words 
"typedef" and "deprecate" in them for me to find it easily.

Basically it was deprecated because it's poorly defined and implemented.
There are several types of typedefs that need to be available: parallel,  
opaque, supertype and subtype.

Would you care to elaborate?  Moreover, if that's the only reason then 
why not improve it rather than getting rid of it?

I see.  So the built-in typedef is closest in semantics to subtype, but 
leaves bits to be desired.
