So feel free to turn that into patch form. This is what I committed. I also updated the Fortran part to add an example and remove outdated info. Feel free to change it (or ask me to change it). +
  • The -Wuse-without-only option has been added to warn when a USE statement has no ONLY qualifier and, thus, implicitly imports all public entities of the used module.
