The following is the current implementation of this function.

toPythonApplication =
    drv:
    drv.overrideAttrs (oldAttrs: {
      passthru = (oldAttrs.passthru or { }) // {
        # Remove Python prefix from name so we have a "normal" name.
        # While the prefix shows up in the store path, it won't be
        # used by `nix-env`.
        name = removePythonPrefix oldAttrs.name;
        pythonModule = false;
      };
    });
