Of course, being a long time supporter of strong typing, I agree with
that view. But if you think in terms of abstract types and problem
domain rather than bits and addresses, don't use C. I see no point in
trying to make a low-level language higher level: use a language
designed to support higher level views.
To take an analogy: nobody would be so fool as to use a language
designed for making animations on web pages in a real-time context ;-)
