It depends. I don't think this is unexpected:


struct Path {
     string value;
     Path opBinary(string op)(in string path) if(op == "/") {
         import std.path : buildPath;
         return Path(buildPath(value, path));
     }
}

void main() {
     assert(Path("/foo") / "bar" == Path("/foo/bar"));
}
