My main use case for pimpl is also to avoid header inclusion, but for a
different reason. When wrapping third-party software, you usually want
to avoid exposing their symbols in your own headers. For instance, you
may have a C header full of macros that could clash with symbols
elsewhere. By limiting the inclusion of those third-party headers to
the .cpp file with the pimpl, you do not pollute the global "namespace".
