Comment (by jdemeyer):

 1. I think you should add a `.pxd` file such that other Cython modules can
 `cimport` this if needed.

 2. Use the standard
 [http://doc.sagemath.org/html/en/developer/coding_basics.html#headings-of-
 sage-library-code-files copyright template].

 3. Remove `__cmp__ = _cmp_` twice (it doesn't work and it's not needed).

 4. You don't actually use this: `from sage.structure.element import
 have_same_parent`.

 5. There is not much point in making `matrix()` a `cpdef` method: you can
 just directly access the `_matrix` attribute from Cython.
