P1787 <https://wg21.link/p1787>: CWG191 and CWG1200 are resolved by defining
unqualified lookup in terms of every enclosing scope.
Wording: If no declarations are found, the results of the unqualified search
are the results of an unqualified search in the parent scope of S, if any, from
P. ([basic.lookup.unqual]/2)
