Better handling of newlines?

[justinabrahms]

In item #4 (json parsing / serializing), I mistakenly had a str.split() instead of str.split('\n') which made a rather difficult error message.

The key here is that the invisible character \n is obscured with an actual newline, which made it difficult to discern the actual error. Escaping it somehow would make that much easier.
