Assignments reset exit status

  set +e
  false
  x=foobar

Assigning exit status works

  set +e
  false
  x=$?
  echo $x

:STDOUT:

Assignments use command substitutions for exit status

  set +e
  x=$(false)
  echo $?
  x=$(true)
  echo $?

:STDOUT:

  1
  0

Assignments update exit status on the fly

  set +e
  false
  x=$? y=$(true) z=$?
  echo $x $z

:STDOUT:
