Comment (by Isaac Dupree):

 are the following equivalent?
 {{{
 a `fseq` \a' -> b `fseq` \b' -> (a',b')
 }}}
 {{{
 b `fseq` \b' -> a `fseq` \a' -> (a',b')
 }}}
 (I guess this is the usual question where the order of strictness doesn't
 matter because "imprecise" exceptions?  but the order might have non-
 obvious performance implications?  It's simpler than `let` because it's
 not mutually/recursive by default...)
