[Python-Dev] Using Cython for standard library? (original) (raw)

Is using Cython for anything in Modules/ really an option? In my limited experiments with it, I did like it.

But using it for Python standard library stuff doesn't look quite right to me: - Option 1: distribute Cython with Python and integrate into build process -- Ouch! Can you be a bit more descriptive? Cython is still being worked on (intensively, it seems). Bundling it with Python means deciding on a particular version probably for an entire major release lifecycle (use Cython x.y.{newest} for Python 2.7, for example).

If we're talking about Cython for core libraries...

For the subset of python that also works in Cython, I've seen a 10-30% performance speedups on (admittedly trivial) test code. Conceivably, everything could be Cython-compiled if you cared about performance more than transparency.
