RULES and strictness

when performing strictness/abscence/one-shot analysis, are rule bodies taken into account? like, would the following cause trouble making const no longer absent in its second argument? const x y = x {-# RULE "const/seq" forall a b . const a b = seq b a #-} by trouble I mean the compiler failing or producing bad code in some way, rather than the obvious trouble of changing the meaning of const. it is noted in the deforestation papers that rules can change the sharing properties of code and we are okay with that. I was wondering if they could safely change the strictness or abscence properties of code as well? John -- John Meacham - ⑆repetae.net⑆john⑈
