Thanks for this clarification.  In my limited understanding of
licenses this would mean that in the Haskell world LGPL and GPL
basically are the same.  I suppose it's an excellent example of just
how difficult it is for "law" to keep up with technology, even when
the "law" is written by technologists.

I guess it means I might as well relicense all my Haskell code under
GPL instead.

I'm also disappointed to hear that the FSF hasn't bothered responding
to this issue.  What part of the FSF was approached?  Does someone
still have copies of the letters/email that was sent?
