Details:

I was battling this problem now for several hours

i wanted to do this:

{ a | b; } & pid=$!

and then later

kill -- -$pid

to kill all the processes spawned by the pipeline.

But this proved to be immensely complicated as no new process group is spawned
from within a script (unless set -m which is not recommended)

Please, provide a syntactic construct to spawn a new process group (or at
least there should be some usable command to do that).
