The second argument of remove() needs to be an index, a size_t.

This works:

import std.stdio, std.algorithm;
struct Loc {
    uint row, col;
}
void main() {
    auto a = Loc(3, 2),
         b = Loc(5, 3);
    auto data = [a, b];
    writeln(remove(data, 0));
    writeln(data);
}


It prints:
[Loc(5, 3)]
[Loc(5, 3), Loc(5, 3)]

So curiously remove() doesn't work in-place, I think this is a bug or a design bug.
