The design is described here: http://hackage.haskell.org/trac/ghc/wiki/OverloadedListsEg. you can use it for maps, so that [(1,"foo"), (4,"bar")] :: Map Int String
So, this has probably been asked before, but out of curiosity, given:
instance IsList Text where
type Item Text = Char
fromList = Text.pack
toList = Text.unpack
What is the relationship to OverloadedStrings? Since "blah" is sugar for
['b','l','a','h'], could OverloadedLists also work for string literals
/ string patterns?
