Migrate from master to main now-ish?
- Branch protection
- Any CI systems we can see that will break
- Keep master and main synchronous for a few days.
- look at what Dask did and copy that
- Pin the issue, wait for 4 weeks, "you have been warned"
Python-3.10 status
- Compiling whole-stack
  - from LLVM source to Numba all based on py3.10
  - most of the hiccups came from building wheels and mixing anaconda binaries

*** #7355 - BUG cannot set items in structured array data types in 0.54.0
- short term: just fix the bug
- long term: open new issue to discuss proper abstraction for Array type and its subclasses.
#7356 - Numba 0.54.0: unexpected assignment behavior within objmode context.
#7358 - Debug output for LLVM loop-vectorize needs an LLVM build with assertions
#7362 - sphinx / numpydoc requires 0.37.0 of llvmlite but doc building requires 0.38.0
#7365 - Variable name uniqueness issue in inlining (introduced in Numba 0.54)
#7366 - Unexpected behaviour of numpy.linspace within am njitted funciton
#7368 - CUDA distance matrix (cdist, pdist, and sparse versions, Euclidean, Wasserstein, etc.)
#7369 - Add np.moveaxis support.
*** #7370 - debugging when JIT a compiled function is derived from string exec
*** #7371 - Support inlining C and C++ (or even LLVM IR) code into nopython-jitted function/class
#7372 - Special operator's methods (like add) don't work in jitclass
#7373 - Support for where= kwarg in ufuncs
#7374 - Add np.putmask support.
#7376 - Instances of undefined behaviour

#7359 - Extend support for nested arrays inside numpy records
#7360 - CUDA: Fix potential leaks when initialization fails
#7361 - Support Boxing LiteralList
#7363 - Update cuda.local.array to clarify "simple constant expression" (e.g. no NumPy ints)
#7364 - Removes an instance of signed integer overflow undefined behaviour.
#7367 - developer contributing docs - llvm, sqlite3, sphinx-rtd-theme, and make html
#7375 - CUDA: Run doctests as part of numba.cuda.tests and fix test_cg
#7377 - CUDA compatible dist_matrix
