I believe that for most people it will feel more natural if foo's type
is not changed to an object or an array.
However I notice with current Firefox (I don't have MSIE, and I'm too
lazy to read the whole ECMA Script specs) that an array with only one
element is represented by JavaScript the same way.
([ "foo" ]).toString().charAt(1)
"foo".toString().charAt(1)
document.write([ "foo" ])
document.write("foo")
Both works the same in each case. Even alert() will display the value of
the first element.
IMO it might be possible to wrap values into arrays without breaking too
much JS code (bools and other scalars will still not work as expected,
and of course an array will not have strings functions) as I think most
uses of json_encode() are for strings escaping.
