Description

It would be very nice to have an ability to output more detailed preview when Parse error will happen.

Currently error message contains only this:

Error: Line 5: Unexpected token ;

It would be nice to have code part in the error message:

Error:
var bark = bar + baz,; <- Line 5: Unexpected token ;
