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 ;

Done means parse errors include the relevant source context without breaking existing error output or tests.
