Description Michael Rennie CLA 2014-02-03 16:08:35 EST 
In some cases Esprima seems to barf and not return a token stream when it encounters a parse error, we should handle these cases and try to hobble together the syntax error for the end-user.

Consider the following snippet:

function(

we still get a parse error from Esprima, but no token stream. You can add that snippet at the end of any JS file and no tokens will be returned. In the [revious example I would expect there to be a keyword token and a punctuator token.
