Fix module links in Haddock comments
They are just like decode and decode' respectively but return an error message when decoding fails.
…a/Aeson/Encode.hs)
depends on text >= 0.11.1.0
Sometimes, it appears, Nullary constructors can be encoded as Null as well as an empty array [not sure why one this!]. The Generic code, as of 49befca, fails when a Null is passed for a nullary constructor. Add in a pattern match to fix this issue.
Someone else released a version claiming to be 0.6.0.1 - boo!
…event XSS attacks
Added an instance for the 'Fixed' class.
parseJSON for the variations on ISO-8601 dates as listed in ECMA-262.
Add functions for inspecting Values
Added eitherDecode and eitherDecode'
Add elaborate guide to Data.Aeson's Haddock documentation
I think the latter is more descriptive.

this requires attoparsec 0.12.2.0 or later to work see haskell/attoparsec#71
(I am wondering how the attoparsec version dependency should be made obvious to everybody. I guess it would be neat to add a note to the error message iff attoparsec < 0.12.2 (is this easy to accomplish with CPP?). If there is any interest in this, I can write another pull request.) |

I'm not sure I understand -- do you mean I should drop the call to eitherResult entirely?
The point of thie change is that (given haskell/attoparsec#71 is merged) the <?>
-comments will actually be shown. Without this change, they will be silently dropped. I've added another commit message to the attoparsec patch that explains this.

(i just stumbled back over this open browser tab, so i tried to replace the case with a >>=, and then i realized i didn't do that because Result and L.Result are two different types. So I think I need another hint.)
This requires haskell/attoparsec#71 to have any impact, but it should work as well before with earlier attoparsecs.
