// all the things from that module into the main module, but we also import our own derive by its
// exact name. Due to the way wildcard imports work in rust, that results in our own derive taking
// precedence over any derive from std. For some reason the named re-export of our own derive
// cannot be in in this (or really any) macro too. It will somehow still consider it a wildcard
// then and will result in this warning ambiguous_glob_reexports, and not actually exporting of our
