I'd argue that -package is a global option and should stay that way.
The only reason you might want to disable -package for certain modules
and not others is if you want to do some tricks with module shadowing -
and this definitely isn't supported in GHC.  You should pass the same
-package to every compilation.

The optimisation options are a different matter.  I agree, they really
should be dynamic.

Arguably -I should be dynamic, but I don't think it does much harm being
static. =20

I think -i is a global option in the same sense as -package, though.

The library options -l and -L don't really matter, since they're only
used at link time and you wouldn't want to put them in OPTIONS anyhow.
