I wonder if there is any way in which we could combine this

myfunc( x : ycoord, y : xcoord, color : blue ) [3]
where the arguments are the wrong way around. Would have to
change the types of the xcoord and ycoord variables somehow,
something I have asked about earlier.
import std.typecons: Typedef;
alias XCoord = Typedef!(int, int.init, "XCoord");
alias YCoord = Typedef!(int, int.init, "YCoord");
auto myfunc(XCoord x, YCoord y) { ... }
Brilliant. Thank you Paul.
