On this note, a useful pattern is

It could be nice to encapsulate this in a context manager.
Absolutely.
I think I'd prefer variable-sized arrays that would always get
deallocated on exit of the function
Why? A context manager is much clearer
That is highly subjective, I think it would be harder to read and
introduce more code blocks and nesting.

the lifetime of the memory.
Yes, but very often you don't need it. And if Cython would support
declarations in blocks you'd get it for free. Supporting that
(disregarding the difficulties of that) would also be helpful in
identifying the scope and privatization rules in parallel blocks.
The thing is that a context manager would be very Cython-specific
Not at all. It's the One Way To Do It in Python.
