You might be accused of dogmatic monolingualism if you don't accept
the notion that some such code may be more naturally expressed in a
higher level language -- that could be one such reason.  Another
reason of course is the fact that it is already done and working:
rewriting costs new effort.

(Note that I'm not asserting that the former reason applies strongly
here; libstdc++-v3/include/bits/demangle.h for example doesn't seem to
rely much on the C++ language's extra capabilities.)
