Subject: Re: [SG10] New issue: <memory> and <execution> should define __cpp_lib_parallel_algorithm
From: John Spicer (jhs_at_[hidden])

The process for fixing things like this is not well defined right now.

In general, the feature test stuff is supposed to be part of the CWG/LWG process.

For fixing things that were missed earlier, I did a paper for a few of those recently.

How would folks like this handled? It could be an LWG issue, or I can write a short paper with this proposed resolution.

John.
