haskell - Can fusion see through newtype wrappers? -

given: newtype myvec = myvec { unvec :: data.vector } deriving (functor, etc) this create (something like) this: instance functor myvec fmap f = myvec . data.vector.fmap f . unvec will vectors fusion rules fire , rewrite fmap f . fmap g $ myvec fmap (f . g) myvec ? are there pitfalls should aware of? afaik problem "pay" new types in containers solved in ghc 7.8, it? fusion rules operate on functions, not on types. functions on myvec won't have fusion rules, unless write them reuse underlying ones. e.g. map :: (a -> b) -> myvec -> myvec b map f = myvec . vector.map f . unvec {-# inline map #-} then we'd have uses: map f . map g which inline to: myvec . vector.map f . unvec . myvec . vector.map g . unvec ghc should erase newtype constructor, yielding regular stream, suitable fusion: myvec . vector.map f . vector.map g . unvec you can confirm running ghc , looking @ rewrite rules firing. alternatively, can add own

we have embedded google map on site. works charm in every browser incl. ie<=10. on ie11, however, under unspecific circumstances, browser jumps (scrolls) after firing load event google map, happens below "fold". ("unspecific circumstances": homepage not exhibit peculiar problem, sub-pages , pages on subdomains reliably, although embedding code identical.) searching web brings this thread in google product forum, that, if nothing else, proves it's not exclusive problem of our site. i searching idea how debug , finding root cause jump. perhaps has found problem, or there (new) config option embedded maps, controls behavior? while don't have "root cause jump" have solution avoid this. can see on site developed , i've implemented lazy loading through use of wordpress plugin bj lazy load. google map iframe doesn't appear in dom till scroll region, "focus" issue never occurs. non-wp sites, can use vvo's jquery
