1643. Default arguments for template parameter packs

Section: 13.2  [temp.param]     Status: NAD     Submitter: Vinny Romano     Date: 2013-03-17

Although 13.2 [temp.param] paragraph 9 forbids default arguments for template parameter packs, allowing them would make some program patterns easier to write. Should this restriction be removed?

Rationale (April, 2013):

CWG felt that removing the restriction was an extension best considered by EWG.

Additional note, April, 2015:

See EWG issue 15.

This is a request for a possibly desirable feature, which should be proposed in a paper to EWG.
