+Caveats and quirks:
 - You may need to manually insert type casts in places where they aren't required by the C standard.
 - At the moment `malloc()` / `free()` don't use a free list, they just leak memory
   - If you would like to help with this, the implementation is in [`include/stdlib.h`](include/stdlib.h)
 - The error messages are currently fairly weak
   - Type errors have no line numbers
   - Errors inside macro expansions have incorrect line numbers
 - The [`printf()` function](include/stdio.h) is only partially supported
