- from future import disable reflected list PR
- ready for review, PRS: #4883 #4937 and #4941
- Functions as first class types progress
- Added FunctionType
- Can't call them yet.
- working on lowering of calls
- #4903: Multiple reductions
- Todd will be opening a PR to fix this
- Should we have an anti-aliasing check in testing to verify that objects are not being reused in the IR.
- Aliasing being introduced in parfor creation. (new var name = expression for numpy exp, and expression was being reused)
- Make IR nodes immutable?
- Stick aliasing check in the legalizer?
- This will uncover a lot of potential issues
- what are the requirements for refcounting in boxing functions?
- not sure, also should add to dev docs
- review what PRs are in and out of release
-
#4939 - comparing ndarray with boolean fails in lowering error
- Stuart has PR (https://github.com/numba/numba/pull/3901) with fix for all of these, except those that require SSA
-
#4933 - Discussion: should
__cuda_array_interface__include a stream pointer?- out of scope, IMO

#4930 - Cannot create jitclass with python list
- type spelling not obvious

- TODO:
- allow typing to pass
- but raise in runtime
- TODO:
-
#4922 - prange reduction incorrect when operation happens inside a conditional block
- PR already opened

Requests for 0.47 (last release for the year) - jitclass performance issues - llvm 9 trial - CTK libcudadevrt.a - CI needs to take 50% of current time - Val & Stu already looking at this - also checking Azure CI config to avoid wasting compute time - Caching: - transitive dependency - other issues: i.e. function as argument,
with objmode- distributing cache - Immutable list and deprecating reflected list - Switch to pytest (see above) - Using Numba to generate LLVM/NVVM IR for different targets https://github.com/numba/numba/issues/4546 -@overloadfor gpu
