You can use `ble/util/assign' in the following post:
https://lists.gnu.org/archive/html/help-bash/2020-05/msg00057.html

  ble/util/assign stderr '
    ble/util/assign stdout "cmd" 2>&1'

It works because `ble/util/assign' executes commands in the same
process without fork.  Actually, there is a use case here:
