17description:
18 A JSON parsing and encoding library optimized for ease of use
19 and high performance.
20 .
21 To get started, see the documentation for the @Data.Aeson@ module
22 below.
23 .
24 Parsing performance on an early 2011 MacBook Pro (2.2GHz Core i7),
25 running 64-bit GHC 7.6.3, for mostly-English tweets from Twitter's
26 JSON search API:

38 Handling heavily-escaped text is a little more work. Here is
39 parsing performance with Japanese tweets, where much of the text
40 is entirely Unicode-escaped.
