A monad that has all the features needed by GHC API calls.
In short, a GHC monad
- allows embedding of IO actions,
- can log warnings,
- allows handling of (extensible) exceptions, and
- maintains a current session.
If you do not use Ghc or GhcT, make sure to call initGhcMonad
before any call to the GHC API functions can occur.
