I never suggest such things.

The difference here is that there has always been one rc (ignoring the=20
UNIX version, which is gratuitously incompatible), unlike the bourne=20
shells. One of the great things about it has always been that you could=20
write rc scripts and know that they'd work on rc wherever they were run.=20
If you start extending the spec, then things start to suck, truly.

It runs on Inferno, which runs on Plan 9. You can script for Plan 9 in=20
Inferno's sh. You can even script for UNIX in it. I've done both. It=20
works. It's not even ugly.

At any rate, someone might write a new shell which is neither es nor=20
Inferno's shell, which is designed to run on Plan 9. I'd still rather=20
just use Inferno's shell, myself.
