Licensing clarity is important for users I think.  But equally some  
users may desire to use LGPL libraries too.  Hence my suggestion that  
there be a separate platform of free/LGPL code (and GPL tools), which  
can depend on the proprietary-friendly BSD-licensed platform, but not  
the other way round.

The static-linking exception is the commonest means of working around  
ghc's technical limitations here.  The exception is part of  
wxHaskell's license (but not Gtk2hs's), and HaXml (+polyparse on which  
it depends) has the exception too.
