Thanks Christian.  I didn't really like those sentences either.  I've
changed them to:

It is _possible_ to write C or Fortran code for use in R, but it will
be painful; Rcpp provides a clean, approachable API that lets you
write high-performance code, insulated from R's arcane C API.

(Feedback is definitely appreciated, but might be better sent to me
directly instead of to the whole list)
