I use a lot of internal, (and inappropriately placed in HAL) macros to simplify various things that are actually generic. Interest in this published as a crate. These all take complicated syntax and reduce is to the semantically meaningful parts.

- Unmask and set priorities for cortex-m NVIC
- Parse a number from a u8 slice
- Write a number to a u8 slice
- Initialize globals in bulk (Mutex<RefCell or Mutex<Cell)
- Access globals in bulk (Mutex<REfcell only; cell syntax is fine as-is)


I use these all over my programs to make them easier to read and write. My gut says most people wouldn't use them because the community is small and mostly uses embassy and other frameworks to manage these. Or postcard to [de]serialize instead of explicit indices. LMK!
