OK, that's a bit confusing -- we have SCM_COMPLEXP which does *not*
mean the same thing as scm_complex_p -- the former checks to make sure
the object, tag-wise, is a complex smob, the latter checks to see if
the object actually contains a complex number, so we have

  (complex? 3) -> #t

but

  SCM_COMPLEX(SCM_MKINUM(3)) -> 0
