Hi,

Note that http://wg21.link/p1389 was written to give advice about what
patterns to use and what to avoid. It is not a document that teaches C++,
it is meta: it gives guidelines to creating C++ teaching materials.

We have since chosen a modular approach as described in
http://wg21.link/p1725
We have a github repository at https://github.com/cplusplus/SG20/ where we
are building modular teaching guidelines following http://wg21.link/P2193
and http://wg21.link/p1725
