Mr. Rockwell's point is presumably that it would be more widely used
were it more widely implemented. I cannot help but agree.
Unfortunately, it is impossible to do cost/benefit analyses on
possible universes of computation in which given tools are more or
less available or efficient. A pity.
I've been taken to task by another reader for my use of the term
"general computing base", since I can't define it. That point is also
well taken.
Things are not as simple as I had believed...
