The way i had handled this in the _busybox function is:

_cmd_variant[${words[1]}]=busybox _normal

That way you can temporarily override what _pick_variant thinks the actual
variant is. This seems to work quite well, but i did feel some guilt about it,
since as you mention it's circumventing the interface.

I was playing with this some more to see if i could come up with a better way
and actually discovered a problem with the method i described: it is not a
temporary override. Apparently pre-command re-assignment of array members
doesn't work the same way it does with scalars — zsh doesn't put the value back
the way it was when it's done executing the command. I assume the same code is
involved here as with the issue i brought up in workers/42097....

I am not actually sure if it is related (workers/42097 = my #4), but maybe. Didn't look into it much.
