The 'Why not LGPL' doesn't cover the particular argument here:
> using the ordinary GPL for a library makes it available only for free programs.
The particular concern we have here is quite specific, considering
(-->) to be a dependency, can Hackage libraries under BSD3 that depend
on libraries under GPL?
 App --> libBSD3 --> libGPL
Any App built has to incorporate the GPL library - so the App has to
be GPL. -- No dispute --.
Similar BSD3 is a GPL compatible library, so this dependency chain
would be legal:
 App --> libGPL --> libBSD
The argument is whether it is legal to distribute (read host on
Hackage) BSD3 libs that depend on GPL libs - formulation .
I'd have thought Harmony would be problematic for different reasons -
i.e. coping the API of a copyright work.
