Alas no, because that would mean that CMD always waits for
CMD_SUB to finish.

What I want is for CMD to do "spawn/nowait @CMD_SUB" and
then exit when called like this:
$ @CMD

or like this:
$ spawn
$ @CMD

But I want CMD to wait for CMD_SUB when called like this:
$ spawn @CMD

or like this:
$ spawn /nowait @CMD
