#4984: Clean up __getitem__ for matrices once Cython is smarter
----------------------------+-----------------------------------------------
Reporter: craigcitro | Owner: was
Type: defect | Status: new
Priority: minor | Milestone: sage-wishlist
Component: linear algebra | Keywords:
----------------------------+-----------------------------------------------
So we currently use several Python/C API calls to speed up the
`__getitem__` method in `sage/matrix/matrix0.pyx`. In particular, we do
several typechecks against standard Python types, and replacing generic
`PY_TYPE_CHECK` calls with specific Python/C API calls (like
`PySlice_Check`) provides a significant speedup. Once Cython can do all
these things for us, we should clean up `__getitem__` so that it's more
readable/portable.
Alternatively, if such functionality still doesn't exist in Cython, one
should feel free to go, implement that functionality, get it merged,
create a new Cython spkg, and then make these changes. `:)`
