#4191: Replace -fstrict-dicts with programmer-custom strictness annotations for
class contexts

---------------------------------+------------------------------------------
Could we perhaps add syntax that looks like
{{{
foo :: (!(Foo a)) => a -> a
}}}
to indicate that a dictionary should be evaluated strictly? At the
moment, -fstrict-dicts is an extremely blunt tool, since it can only be
given as a static option.
