Perhaps, in light of Oz's reply, I need to make it clear that
I was not trying to say or imply that _he_ though languages did
force programmers to use the exception system, and similarly
for a number of other things he may have had in mind when
writing

(I don't know what he did have in mind there, though I took a 
stab at one possibility above.)

Still, I did misunderstand some things about his message in ways that
are revealed by his reply.  For instance, I didn't realize that he
meant for C++ to be seen as providing some relevant help.
