Notes from the May, 2015 meeting:
CWG agreed that such techniques should be ill-formed, although the mechanism for prohibiting them is as yet undetermined.
Defining a friend function in a template, then referencing that function later provides a means of capturing and retrieving metaprogramming state. This technique is arcane and should be made ill-formed.
