Re: Revisiting Error handling (errexit)

[Martin D Kealey]

Modules can have conflicting requirements of global settings that require
weird contortions to interoperate; so starting out by making this yet
another global setting seems like a retrograde step.

So I would like to propose an alternative approach.

Firstly, I would reduce the action to simply "return from function upon
unchecked failure"; the issue is primarily with *invisible* behaviour at a
difference making this difficult to debug.

Secondly I would set this as a per-function attribute, rather than as a
global setting outside the function.

Perhaps

function -E funcname { … }
