Now my deeply thought question is ...
Is typedef (in D) a C/C++ legacy or is the dear orphan now adopted as a
first-class citizen in the US of D?

Typedef works differently in D. It should create a new type, in C++ it's
just a type synonym.
Exactly, it's most useful to create specialized types from primitives.
For example I declared the HANDLE type in my win32 bindings as "typedef
const(void)* HANDLE;" and all its specialized types (HWND, HMONITOR,
HDC, etc) are also typedefs of HANDLE, so I have very little chances of
misusing them. The only downside is that I must use HWND.init instead of
null, but that's just giving better readability to function calls.
This is something you just can't do in C.
