This is vaguely reminiscent of a SO comment I ran across recently: http://stackoverflow.com/a/27962571, which really opened my eyes to the powerful combination of variadic templates and tuples. OP's guide is very informative in breaking things down, kudos; but I also suggest checking out that SO comment as it's a more barebones exposition of variadic templates + tuples (no threading, no watching, etc).

He/she did not state anywhere that the government should ban them.

I highly suggest avoiding pictures of a teratoma. It's something that cannot be unseen.
