1900. Do friend declarations count as “previous declarations”?

Section: 9.3.4  [dcl.meaning]     Status: CD6     Submitter: Hubert Tong     Date: 2014-03-25

[Accepted at the November, 2020 meeting as part of paper P1787R6 and moved to DR at the February, 2021 meeting.]

Issue 1477 assumes that a name declared only in a friend declaration can be defined outside its namespace using a qualified-id, but the normative passages in 9.3.4 [dcl.meaning] paragraph 1 and _N4868_. [namespace.memdef] paragraph 2 do not settle the question definitively, and there is implementation variance. A clearer statement of intent is needed.
