1691. Argument-dependent lookup and opaque enumerations

Section: 6.5.4  [basic.lookup.argdep]     Status: C++14     Submitter: David Krauss     Date: 2013-05-27

[Moved to DR at the February, 2014 meeting.]

Proposed resolution (September, 2013):

Change 6.5.4 [basic.lookup.argdep] paragraph 2 as follows:

...The sets of namespaces and classes are determined in the following way:

This resolution also resolves issues 1690 and 1692.
