[Haskell-cafe] Chaining a map over lists with lenses

[Daniel Trstenjak]

Hi Nicola,

there's 'traversed' to access every entry of a traversable structure,
e.g. appending a "X" at the end of each 'otherField':

   t & myField . traversed . otherField %~ (++ "X")


And there's '^..' to return a list of each entry of a traversable structure:

   t ^.. myField . traversed . otherField


Greetings,
Daniel
