OK, I noticed this is a compiler issue.

Usually D compiler automatically generates toHash member function by using
TypeInfo.getHash function. But in particular case it had not worked.


Reduced test case:

struct RefCounted(T)
{
    struct Impl
    {
        T data;
    }
    Impl* impl;

    @property ref T payload() { return impl.data; }

    alias payload this;
}

struct HTTP
{
    struct Impl
    {
    }

    RefCounted!Impl p;
}

void main()
{
    int[HTTP] aa;
}

The root problem is very similar to issue 14806.
