fmap . fmap is close to applicative ?
is it possible to do applicative instead of combining 2 fmaps ?
Thanks

How does one write
fmap (fmap (*2)) xs
without parenthesis? (Using . and $ instead.)
I don't really understand . and $ well enough I guess. I tried a bunch of stuff but nothing worked.

fmap . fmap $ (*2)
or perhaps:
(fmap . fmap) (*2)
