I never suggest such things.

The difference here is that there has always been one rc (ignoring the 
UNIX version, which is gratuitously incompatible), unlike the bourne 
shells. One of the great things about it has always been that you could 
write rc scripts and know that they'd work on rc wherever they were run. 
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 
Inferno's sh. You can even script for UNIX in it. I've done both. It 
works. It's not even ugly.

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