# F2PY future plans

1. Typing improvements, union of type with `int | str` requires Python 3.10+
2. `rules.py` settings generation in `f2pyarg.py`
4. Improve F2PY's help message.

## Post distutils deprecation changes
- [ ] Handle `--opt, --arch, --f77flags, --f90flags` in more efficient way.
- Currently they are passed directly to the Fortran compiler.
- [name=Ralf] suggests that handling f77 and f90 seperately and providing compiler paths is unnecessary in his comment here - https://github.com/numpy/numpy/pull/22225#discussion_r966761955
- I agree with him and suggest that F2PY should deprecate `--f77exec` `--f90exec` `--f77args` `--f90args`
