-- Static flags
-- | Parses GHC's static flags from a list of command line arguments.
--
-- These flags are static in the sense that they can be set only once and they
-- are global, meaning that they affect every instance of GHC running;
-- multiple GHC threads will use the same flags.
--
-- This function must be called before any session is started, i.e., before
-- the first call to 'GHC.withGhc'.
--
-- Static flags are more of a hack and are static for more or less historical
-- reasons. In the long run, most static flags should eventually become
-- dynamic flags.
--
-- XXX: can we add an auto-generated list of static flags here?
