RFC 4627 says "A JSON parser MAY accept non-JSON forms or extensions." and
implementations that are compatible with ECMAScript are common enough that
it seems this extension to RFC 4627 actually doesn't cause problems with
applications expecting only arrays or objects at the root.

Does anyone have examples of this behavior creating problems in the wild?
They must be out there, since support for this extension is so common.
