Also, no matter what the language, yet another problem quickly becomes
apparent if you really start doing something like the suggestion (I
one actually did, ahem...)  The suggested model assumes each of the
code snippets are both self-contained and correct.  The first
assumption will trip us if a later snippet requires something from
previous snippets to compile.  The second assumption: how does one
demonstrate *illegal* code if the requirement is that each code
snippet should compile okay? (whatever that means for shells,
I don't know)
