Why not support Tuple indexing and slicing with [] syntax?
 (see below for a way to index/slice a tuple)

void main(){
  alias T=Tuple!(int,double);
  pragma(msg,T[0].stringof);//_expand_field_0
  //pragma(msg,T[0..2].stringof); //Error: cannot slice type 'Tuple!(int,
double)
  pragma(msg,typeof(T.init[0]).stringof);//int
  pragma(msg,typeof(tuple(T.init[0..$])).stringof);//Tuple!(int,double)
}

You need a syntax like:
a.slice!(1, 3);

I don't know why Walter didn't add support for a slicing syntax for tuples. But it's an additive change, so it's not too much late to add it, if it's feasible.

If D will grow built-in tuples (that currently is among my top enhancement requests for D), probably the slice syntax will be supported.
