Note that tools such as ccache and sccache generally need to be able to
understand what's going on (I believe distcc and other distributed
compilation tools also generally need to know too), so making it
sensible enough for interpretation based on just the flags to be
possible should be considered.

For prior art, there are scoping operators for Linux's `ld`:

  - `-(` and `-)` (`--start-group` and `--end-group`)
  - stateful flags like `--no-as-needed` and `--as-needed` that change
    how future arguments are interpreted
