Description ryan 2015-04-03 02:50:55 UTC 
JSONValue(["val" : float.nan]).toString yeilds `{"val":nan}`.
'nan' is not wrapped in quotes.

However, if you call parseJSON on this string, it fails:
"Found 'a' when expecting 'u'" (I guess its trying to parse 'null').

I would expect std.json to be able to parse the strings it outputs.

according to this discussion, it seems that the problem appends when the value is written: "null" should be written instead of "nan":

http://tools.ietf.org/html/rfc4627

" Numeric values that cannot be represented as sequences of digits
   (such as Infinity and NaN) are not permitted."
