Well one thing that I can think of is, are helper methods.

Currently, one is forced to do:

cdef class MyClass
cdef int myhelper(MyClass self, args):
   ...
cdef class MyClass:
   ...
   ...
   # somewhere here:
   myhelper(self, "args")
   # and actually it would read much nicer
   self.myhelper("args")

Basically the current design doesn't allow one to keep all the needed
helper in one place.
And no, having these helpers is the idea in using a Pyrex builtin, so
that reading one character from the input buffer is fast (no string
objects to create, no python method call, etc.).
