I am trying to make a `Pos` type. But I need it to implicitly
cast from an `int[2]`.
I am using the `alias this` to get most of what I want but it
still doesn't do all an implicit cast can do.
What I have now is this:
struct Pos {
int[2] pos;
alias pos this;
this (int[2] pos) {
this.pos = pos;
}
}
This allows me to implicitly cast from type `Pos` to type
`int[2]` but not the other way. I can do a sort of cast when I
define a `Pos` (`Pos pos = [2,3]` works).
But what I really want it to do is to implicitly cast an `int[2]`
to a `Pos`.
Is this possible in D?
