I feel much the same way, but the recent modifications to Cython that
provide a "pure Python"[1] approach mean that you can minimise the
amount of C you need to write and still take advantage of features
like static types:

@cython.locals(s=cython.double, i=int, n=int)
def harmonic_sum(n):
     s = 0
     for i in range(1, n+1):
         s += 1.0 / i
     return s

The same code will both run in Python and compile via Cython. (I'm
surprised the new "pure" approach isn't more clearly promoted on the
