Agenda

Agenda * HPy release 0.0.4 * Autogen: separate API and ABI (context) * HPy binary compatibility

• Assuming that our ABI will always be backwards compatible is a bit naïve. We should start thinking about how to deal with that.
• Inspired by SDL2 paper: https://www.reddit.com/r/linux_gaming/comments/1upn39/sdl2_adds_dynamic_api_magic_to_allow_updating_it/ (sorry, couldn't find the original paper)
• We should think about a policy for supported HPy ABI versions

• Debug mode: The possibility to decide per module makes implementation complicated. Maybe a global decision would be enough (i.e. all contexts are debug contexts or none).

• NumPy Progress and Plans

  • Metaclasses support for heap types in CPython.
  • Extend other builtin types with pure HPy types (e.g. dtype meta inherits PyType_Type, numpy scalars inherit Python builtins) for pure HPy universal mode.
  • Create binary that can run the e.g. all of the code in a [NumPy Game of Life](https://github.com/rougier/numpy-tutorial/blob/master/scripts/game-of-life-numpy.py)
