'eval' in IE will not return function values, therefore json data == "function() {}" doesn't work.

Related to #1298 and [2092] - the fix breaks evaluation of functions in "json" data...

Ex: eval("(function() {})") returns undefined in IE

Technically this isn't really JSON data, but isn't even dealt w/ by any other dataType except by taking it in as text and eval-ing it with the old method.... so long as you don't "pack" it... (though I suppose doing the following works ... but is ugly....

eval("data = function() {}"); data = eval("data")

That does that happen for functions inside json objects ? or only for "just-one-function" responses ?

data = eval("false || (" + data + ")");

works with "function() {...}" as well as any other expression.

Yeah, I don't think we can guarantee arbitrary expressions as JSON when, in fact, they aren't JSON.
