Library Typedefs are fundamentally broken

To implement a typedef in library code in D perhaps you need a 
well implemented __gensym__ that works correctly in presence of 
separate compilation. It can generate a string that contains a 
progressive number for each D module, plus a digest of the module 
path and name.

Phobos contains hundreds of things, but a large percentage of 
them doesn't attract the amount of critiques that Typedef has 
received in many threads. This can suggest you that there is 
something special in Typedef.

This is not surprising because you say you have not used Typedef 
much in your code.
