My mistake. The reason for the template error message was another 
than I though of. Thanks.

I'm aware of `std.string.indexOf` but that's only for strings.


I don't see why canFind isn't good enough for you, maybe I don't 
get what you want:


void main(string[] args) {
import std.algorithm: canFind;

struct Coord {
int x, y;
}

Coord[] list = [Coord(0, 0), Coord(3, 14), Coord(1, 2), 
Coord(4, 2)];


assert( list.canFind(Coord(3, 14)));
assert( list.canFind(Coord(4, 2)));

assert(!list.canFind(Coord(4, 3)));
assert(!list.canFind(Coord(-1, 3)));
}
