I can accept that.

Ok.

So it is not advisable to integrate cpphs in ghc. I have no problem with
that.

Could we, instead, make it easy to use cpphs as drop-in replacement for
cpp, so that it gets used whenever when the CPP language pragma is in
effect? On platforms where the standard CPP is the one by GNU, cpphs
could even be made the default.
