774. Can a closure class be a POD?

Section: 7.5.5.2  [expr.prim.lambda.closure]     Status: CD2     Submitter: John Spicer     Date: 11 February, 2009

[Voted into the WP at the July, 2009 meeting as part of N2927.]

The current wording does not state under what conditions, if ever, a closure class is a POD. It should either be explicitly unspecified or definitively stated that a closure class is never a POD, to allow implementations freedom to determine the contents of closure classes.

Notes from the March, 2009 meeting:

A closure class is neither standard-layout nor trivial.

Proposed resolution (July, 2009)
