Bug 0000770: Add support for .ONESHELL in make OPEN http://austingroupbugs.net/view.php?id=770 We discussed this bug. ACTION David A. Wheeler to propose a new set of changes that add .ONESHELL just as a per-rule feature, not global. Bug 0000771: Expose alternate shell function usage to scripts Rejected http://austingroupbugs.net/view.php?id=771 This was discussed at length during the November 21, 2013 conference call. Other bug reports providing for shell variable scoping (such 0000767 which proposes adding a local special built-in utility) provide most of what is requested here, even though it might not be as efficient as what the submitter desires. But, local is already implemented and is in use in scripts while the new feature requested here is invention and has several open issues about what should be done in certain cases. If there is a strong need for this functionality, the submitter needs to convince the maintainers of POSIX-conforming shells to implement and document this functionality and then propose standardizing that feature in a future revision of the standard. Next Steps ---------- The next call is on December 5, 2013 (a Thursday) Calls are anchored on US time.
