Having said that, though, the success of 'alias this' does

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 ;)
