Hi Jakub,
Your problem is not with templates.
Here's your problem in a nutshell...
struct A
{
int x;
struct B
{
A a;
};
};
You cannot use A within B, because at that point A is incomplete.
You can pull B out of A. If you want B to be in the A namespace, change
'struct A' to 'namespace A', and make 'struct A_impl', fully declared, and
then use that within 'struct B'.
