This is an unofficial snapshot of the ISO/IEC JTC1 SC22 WG21 Core Issues List revision 112e. See http://www.open-std.org/jtc1/sc22/wg21/ for the official list.
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.
