As an aside: are you aware of the problems using LGPL in the context of
GHC statically linking libraries by default (in that they degenerate to
GPL, or require significant extra workaround).

I'm concerned the burden for satisfying the LGPL while GHC statically
links Haskell libraries is too great to impose.
