  I'm pretty sure that any case can be achieved with the current behaviour,
but I agree that ugly contorsions are necessary for more than one case,
so I'm ok to add an option switch - but the semantics need to be right
(and it won't be -z, which I prefer to only use for something related to
reaping z-ombies)

  What exactly is the behaviour you want:

  - don't exit on error, just keep exec'ing
    + do you just define "error" as the subprocess exiting anything else
than 0 ?
  - but completely undefine the variable, in order for later tests such
as importas to pick that up?

  Is that right, or have I missed something?
