Bug #4244: Psych.to_json generate incorrect JSON
http://redmine.ruby-lang.org/issues/show/4244

Author: Tomoyuki Chikanaga
Status: Open, Priority: Low
Category: lib
ruby -v: ruby 1.9.3dev (2011-01-01 trunk 30447) [x86_64-darwin10.5.0]

Psych.to_json could be presumed to return JSON because of its name.
But Psych.to_json generate single-quoted string. It isn't valid JSON format.

>> require "psych"
=> true
>> Psych.to_json("aaa")
=> "'aaa'\n"
>> Psych.to_json(["a","b","c"])
=> "['a', 'b', 'c']\n"
>> require "json"
=> true
>> JSON.parse(Psych.to_json(["a","b","c"]))
JSON::ParserError: 376: unexpected token at ''a', 'b', 'c']
'
