Forget to mention that I want the assign call (to `opAssign`) in `main` to be non-(GC)heap allocating like when using C++'s std::initializer_list.

Hereh we go ;)

struct AA

    void opIndexAssign(int v, string k) @nogc
    {}
}

void main(string[] args) @nogc
{
    AA myCustom;

    enum literal = ["one":1, "two":2].stringof[1..$-1];
    enum pairs   = literal.split(',').array;
    static foreach (p; pairs)
    {
        myCustom[mixin(p.split(':')[0])] = mixin(p.split(':')[1]);
    }
}
