Hack idiom-brackets using Source Plugin.

As nobody (?) writes their lists as `([1, 2, 3])`, we can steal that syntax!

```haskell

{-# OPTIONS -fplugin=IdiomsPlugin #-}

module Main (main) where

main :: IO ()

main = do

    -- Just "foobar"

    print ([ mappend (Just "foo") (Just "bar") ])

    -- Nothing

    print ([ const (Just "foo") Nothing ])

    -- Just 3

    print ([ (+) (Just 1) (Just (2 :: Int)) ])

```
