Having said that, though, the success of 'alias this' does raise some
interesting questions about how useful the concept of a typedef is.
Certainly it's much less useful than when Typedef was created.
My feeling is that almost every time when you want to create a new
type from an existing one, you actually want to restrict the
operations which can be performed on it. (Eg if you have typedef money
= double; then money*money doesn't make much sense). For most typedefs
I think you're better off with 'alias this'.
If you have a look at our transition.d it does exactly that right now -
mixes in the struct with the same name as typedef had and does `alias
this` for its value field ;)
So why not mix in Typedef? -- Andrei
