Fwd: Optional control over 0D array return behavior in PyArray_Return
by Breno Augusto Favaretto April 12, 2026

April 12, 2026

Hello NumPy developers, I would like to propose an optional mechanism to control the behavior of 0-dimensional array return conversion in PyArray_Return. Currently, 0D NumPy arrays are automatically converted into Python scalars in many operations. In some workflows, it is desirable to preserve the ndarray object instead. Proposed idea: - Introduce an opt-in mechanism (initially implemented as a global flag) to control whether 0D arrays are converted to scalars or preserved as ndarray objects. - Default behavior remains unchanged for full backward compatibility. Motivation: In certain array-centric workflows, implicit scalar conversion of 0D arrays can lead to loss of consistency when uniform ndarray behavior is desired. I have implemented a prototype PR here: <https://github.com/numpy/numpy/pull/31221> However, I was informed that this kind of change requires prior discussion on the mailing list before proceeding further. I would appreciate feedback on: - whether this direction is acceptable - whether a global flag is appropriate - or if an alternative design (context-local, function-level, etc.) would be preferred Thank you for your time.

SPy: a new companion static language for Python; thoughts?
by PIERRE AUGIER April 8, 2026

April 8, 2026

Hello, Do any of you follow SPy (https://github.com/spylang/spy), the new statically compiled variant of Python created by Antonio Cuni? I have been looking into it recently and became convinced it could have a significant impact on the Python ecosystem, including for numerical computing and libraries like NumPy. I wrote up my thoughts in a post entitled "SPy: a vision for its impact on the Python community": https://fluiddyn.pages.heptapod.net/spy-book/impact-on-python/ I would be very interested to hear what this community thinks, both about SPy itself and about the ideas in the post. Best, Pierre Augier (CNRS researcher in fluid mechanics, Grenoble)
