Is there a cleaner way to write this function?
import Control.Monad
f :: (Monad m, Traversable n) => m (n a) -> (a -> m b) -> m (n b)
f m g = let
intermediate = fmap (fmap g) m
in
intermediate >>= sequence
Example:
λ: f (Just [1,2,3]) (\x -> Just (x + 100))

I recently noticed this bug while visiting a new site:
Having the beanie overlapped like that is rather annoying to be honest. Not sure if it is a wrong z-index value or relative positioning issues.
Another way to do this would be to use __getattr__().
class Wraps(object):
def __init__(self, *args):
self.things = args

def each(*args, **kwargs):
for thing in self.things:
getattr(thing, item)(*args, **kwargs)
return each
def some_re...
