I think first class tuples will happen in D, because the current 
tuple situation is quite bad.

But this thread is not about built-in tuples, here we are 
discussing about possible improvements to the Phobos 
implementation of tuples.

A possible solution is an optional "@structural" attribute for 
structs that gives structural typing to one struct (that will be 
used as underlying implementation for library-defined tuples.
