Reduced test case:

struct BigInt {}

alias AliasSeq(T...) = T;

template Tuple(Types)
{
    struct Tuple
    {
        Types expand;
        alias field = expand;
    }
}

void main()
{
    alias Foo = Tuple!BigInt;
    Foo[BigInt] cache;

    auto x = Foo();

    BigInt[] arr;
    foreach (y; arr)
        cache[y] = x;
}
