It should also be the case that if you refrain from using -O
then GHC won't export any of its internal symbols, and you
should get much less recompilation. If you want more optimisation,
then more info gets percolated from one module to another, so
more recompilation is ncessary if you make changes. At least
that is the tradeoff that GHC tries to give you.
