jump-starting parser development:
- numeric forms (:class:`integers<integer>`, :class:`reals<real>`,
:class:`scientific notation<sci_real>`)
- common :class:`programming identifiers<identifier>`
- network addresses (:class:`MAC<mac_address>`,
:class:`IPv4<ipv4_address>`, :class:`IPv6<ipv6_address>`)
- ISO8601 :class:`dates<iso8601_date>` and
:class:`datetime<iso8601_datetime>`
- :class:`UUID<uuid>`
- :class:`comma-separated list<comma_separated_list>`
- :class:`url`
Parse actions:
- :class:`convert_to_integer`
- :class:`convert_to_float`
- :class:`convert_to_date`
- :class:`convert_to_datetime`
- :class:`strip_html_tags`
- :class:`upcase_tokens`
- :class:`downcase_tokens`
