For a stable ABI -- of any flavor -- incref and decref will need to be functions, and so they'll be relatively expensive. We should allow minimizing their usage.

We're missing ways to:

• Export Python containers to an array of PyObject* (strong references)
  • Preferably in batches (one by one iteration is too slow, everything at once eats memory)
  • Preferably with an option to convert to raw integers
• Mass decref an array of PyObject*
• Mass incref an array, to pass it on
