Re: Revisiting Error handling (errexit)

The old errexit explicitly exempts any command prefaced by ! which is
important so that one can write ! (( x++ )) without it blowing up when x is
0 and without paying the penalty for  "|| true".
Does this new proposal honour that?

Aside from that, I still think that yet another global setting is
perpetuating the "wrong direction"; "local -" has the same dynamic scope as
any other "local", which means magic action at a difference, and makes
brittle code that can abort unexpectedly in production.
