D with experimental features like tuple unpacking

[Rob T]

I would like to see tuple syntax and abilities improved. It's 
been a while since I last tried to use them so I'm not prepared 
to explain in detail what I'd like to see for improvements, 
however I can say that when I did try to use them I remember they 
were much more unwieldy to use and more limited that I thought 
was necessary.

I tried to use them for named parameters and for a function that 
could return multiple results, both without resorting to structs, 
but those attempts failed.

I basically wrote tuples off as too complicated and awkward to 
bother with and have not attempted to use them since, but that is 
unfortunate.
