P1787 <https://wg21.link/p1787>: CWG562 is resolved by defining lookup as
occurring from a program point.
Wording: A single search in a scope S for a name N from a program point P finds
all declarations that precede P to which any name that is the same as N
([basic.pre]) is bound in S. ([basic.lookup]/2)
