This is an appropriate place to discuss things such as whether and how
an extension could be implemented in a way that the compiler still
conforms to the C standard. However, extensions themselves do create a
new language. You could, for instance, have a compiler that has an
extension that interprets  "#pragma lang pascal" as switching the
language from C to pascal (I don't know pascal well enough to suggest
the appropriate approach for switching back to C, but I assume it could
be done). Do you think that would justify engaging in long discussions
about pascal in this newsgroup?
