Bump!
It might be a good idea to p.mask this when it goes into the tree to make sure it doesn't break portage.
this wont be usable until pipeline and set -e get sorted out on the POSIX lists http://lists.gnu.org/archive/html/bug-bash/2009-02/msg00043.html
bash-4.0 is available.
people prob want to avoid this as it clearly barfs on our eclasses /usr/portage/eclass/eutils.eclass: line 1720: syntax error near unexpected token `;;' /usr/portage/eclass/eutils.eclass: line 1720: ` *) die "unknown action '${missing_action}'";;' added to the tree at any rate ;D
