The problem with this syntax is that currently =E2=80=98start=E2=80=99 proc= edures can take an arbitrary number of arguments: herd start foo x y z means that the =E2=80=98start=E2=80=99 procedure of foo is passed x, y, and= z as arguments. It=E2=80=99s occasionally useful and we do have a few System/Ho= me services that use it (=E2=80=98home-pulseaudio-rtp-sink-service-type=E2=80= =99, =E2=80=98guix-service-type=E2=80=99, =E2=80=98documentation-service-type=E2= =80=99 in the installer). So I think we can=E2=80=99t just remove support for that syntax. Not sure how to improve on that. Ludo=E2=80=99.
