Challenge: reimplement `foo` such that above unittest will compile. No cheating with malloc etc. Bonus points if you don't have to implement a modified version of std.algorithm.map

import std.algorithm, std.range;

auto foo(R)(R a, immutable int b)
{
    return a.map!(x => x + b);
}

@nogc @safe unittest
{
    int[3] test = [1,2,3];

    assert(test[].foo(3).equal(only(4,5,6)));
}

does this count?
