If you are loading Haskell code, you will need to be very careful to
make sure you load all of the dependencies as well. There are a number
of plugins packages and a paper:
GHC API changes a lot, so it's easy for these packages to get bitrotted.
The upcoming release of GHC will run constructors (link-time
initializers), but will not run destructors.
There is only partial support for weak symbols. http://ghc.haskell.org/trac/ghc/ticket/3333
