Re: search.c clean-up
A separate issue is making the decision as to which apps are worth
rewriting in C++, vs. just pushing forward with what's there. E.g.,
I dunno that I want to put a lot of time into redoing gawk in C++.
Grep is a smaller program, though.
it's not like the whole program would need rewriting. that's the
advantage of Stroustrup's compatibility tradeoffs: we can just rewrite
bits as they cause us trouble or are getting rewritten anyway for other
RAII is reason enough to use C++ on any program more complicated than
