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);
}
