Arity is smaller than need be
Consider
h x = let f = case x of { True -> t1; False -> t2 }
in (f,f)
where t1
and t2
have arity 1. You'd think that f
should have arity 1, but it doesn't. (Reason: exprArity
, used in Simplify.addNonRecWithUnf
, doesn't look through the case.)
Fix this as part of the upcoming arity cleanup.
