I suggest Haskell introduce some syntactic sugar for Maps.
Python uses {"this": 2, "is": 1, "a": 1, "Map": 1}
Clojure also use braces: {:k1 1 :k2 3} where whitespace is comma but
commas are also allowed.
I find the import Data.Map and then fromList [("hello",1), ("there",
2)] or the other form that I forgot(because it is to long!) to be to
long...
So why not {"hello": 1, "there": 2} ?
it is hard to see much benefit over something like this:

x ==> y = (x,y)

myMap = fromList [
        "hello" ==> 1,
        "there" ==> 2
        ]
