If `foo(int, int)` is defined to be literally the same as `foo(int[2])`, 
there is no conversion. But anyway, I guess you'd also consider anything 
that would make this work an "implicit conversion"?

double foo(int x,string y);

writeln([(1,"2"),(1,"3"),(3,"4")].map!foo);

If so, maybe one way to make _some_ progress on this is to have a DIP 
specifically for destructuring, without adding any new types?
