- The lexer did not jump to the `heredoc_end`, causing the heredoc end delimiter
to be parsed twice.
Normally the heredocs get flushed when a newline is encountered. But because
the newline is part of the string delimiter, that codepath i... -

In the case of surogate pairs we consume two backslashes, so
`json_next_backslash` need to ensure it's not sending us back in the
stream.

Since Python's `str.strip` takes an optional argument, it might be a good idea to introduce a similar feature.

- Since we do a decent job of pre-sizing objects, don't handle the case where we would need to re-size an object. Also don't handle too-complex shapes.
