Actually, I would suggest that C++ migration for the sake of C++ migration
is not worthwhile. The advantages are offset by the temporary surge in bugs
and the fact that the rewrite is probably done by somebody with imperfect
understanding of the module rewritten.

The best approach, IMHO, is to change each module to C++ as each module sees serious
change -e.g., the person making significant algorithmic changes gets to move things
to C++. That minimizes the negative impact, since it means that people who understand
each module will do the job on that module.
