🏃 Sprints meta-issue

[Zac-HD]

This weekend is the SciPy 2022 sprints (and EuroPython sprints!); if you're keen to contribute to Hypothesis, apply Hypothesis to other sprinting projects, or work on some related issues, you're in the right place. How this works:

1. Talk to Zac about which of the issues below you might work on, and we'll reserve it (check the box)
2. Fix the issue, make a PR, and iterate on it.
3. PR gets merged, celebrate!

Hypothesis issues

• [easy] math.isfinite, isnan, and isinf filter-rewriting from Return efficient strategies for simple filter predicates, instead of rejection sampling #2701
• [easy] Add allow_subnormal= param to the complex_numbers() strategy allow_subnormal keyword for complex_numbers #3390
• [easy] Ensure warnings point to user code Set appropriate stacklevel= in all calls to warnings.warn() #3403
• [easy] Improve Ghostwriter CLI error message Better error messages for hypothesis write <some_filename> #3404
• [easy] Numpy new prng support Add a strategy for new Numpy PRNGs #3131
• [inter] Hit integer bounds more often st.integers() never generates examples close to the max_value #2942
• [inter] Pandera efficiency issue Make Hypothesis strategies more efficient with statistics resolver and reducing use of .filter() unionai-oss/pandera#404
• [inter] AST-based warning for @st.composite misuse Warn when an @st.composite strategy doesn't use the draw() function #3384
• [inter] annotated-types constraint support: Check for annotated-types constraints in st.from_type(Annotated[T, ...]) #3356

With the sprints over, it's time to close this meta-issue - until next time. Thanks again to everyone who helped out here or in other projects, for your contribution and the fun we had together!
