My own C standard library
- characters processing:
- base64 facility
- unicode normalisation facility
- string formatting (templating)
- data structures:
- tree structure
- linked list/vector
- ring buffer
- format
- json
- url parsing
- numeric
- proper interface for signed integers with overflow handling
- bigint
- bigdecimal
- date
- UTC date ease
- easy to make timezone aware things
- assertions
- I'd like to assert an entire block
- I'd like to have formatted messages (likely a combine of assert and printf)
