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)
}

This works:

import std.typecons : Tuple, tuple;
void main() {
alias T = Tuple!(int, string, float);
T a;
Tuple!(int, string) b = tuple(a[0..2]); // Slicing values.
Tuple!(T.Types[1..3]) c; // Slicing types.
}
