-But they often get a pointer to a buffer which they modify and return
-the success of an operation (or number of modified elements or
-whatever). The basic point is that C and C++ are different languages and
-that this results in different programming styles and different

who's justifying it? I'm merely pointing out that one cannot assume f(x)
not modify x (and you agreed).

I don't think we should use inexperienced users' opinion to justify the
design of
a C++ interface (or any interface).

C++ is not a pure functional language and inplace mutating algorithms are
all over the place.

I don't have more to say about this; I acknowledge that you have a different
view and
I agree it would be nice to hear other people's opinion.
