Hi Eliot,

Actually, I was only joking. Somehow Tim seems to bring that out in me.
But see below.

Well, this is a completely silly idea that nobody would ever bother using
using even it if did exist. And it was a nice sunny Sunday afternoon here
in Michigan, I had a good pot of coffee at hand, so what the heck - I just
went ahead and implemented it. After all, it's not as though the syntax
mashup could possibly get any worse, so why not?

If you update your CommandShell package to the latest version, you can now
use ExternalCommandShell to do wonderfully useless things such as this:

    lewis at lewis-Gazelle-Pro:~/squeak/Squeak5.1$ run squeakSpur64.image
    
    sqsh> 3 + 4
    7
    sqsh> 3 + 4!
    7
    sqsh> 3\
    + 4!
    7
    sqsh> exit
