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))); }

Searching for a T in a T[]
Is there now algorithm (similar to `canFind`) that can search for a `T` in a `T[]`? Existing `canFind` only supports sub-sequence needles. I'm aware of `std.string.indexOf` but that's only for strings.
