I was kind of hoping for some magical D variadic alias template on Tuple or something that will just deconstruct the arguments in to tuple components.

i don't think it's better but :

oops sorry, compile time ...

import std.stdio, std.string, std.algorithm, std.conv, std.range;
import std.typecons;

alias Point = Tuple!(int, "x", int, "y");
enum data = "1,2:8,9";

auto points = data.split(':')
                  .map!( a => a.split(',').map!(to!int).array )
                  .map!( (da) {
                      int[2] staticArray;
                      foreach (i, el; da)
                          staticArray[i] = el;
                      return staticArray;
                  } )
                  .map!Point ;

void main()
{
    writefln("points : %s", points);
}
