We can use clang-tidy and its fixits to modernize code.

I think that we could also do this:

  • Remove magic constants.
  • Break huge functions in smaller ones with meaningful names.
  • Take into consideration the compiler warnings and solve them as much as possible.
  • Take the opportunity to improve the libraries' documentation.
