FWIW, at least for me, this is not a language choice issue, this is an
issue of making a decision whether to invest a non-trivial amount of
time and effort into refactoring.  I would say the same things I did
in this thread if someone would suggest to refactor GDB in C.

For the record, on my daytime job we develop and maintain a very large
body of extremely object-oriented C++ code.  So much for me being on
``the latter side''.
