I think check lists should be their own thing.

A checklist should be the last element in a list.

•••[] This is a sublist.

Also, to simplify the ordered list we should just support the '#' character.

When implementing the parser for this came across another issue. And think it make sense to treat list like block elements:

§§ Lists as blocks

Should lists be a block. There are some interesting
issues that arise from lists.

1. How/when are they terminated?
2. How do you control numbering styling?
3. Should a list be split across pages?

All of these are difficult to answer with the current
layout of lists. However, if a list as a block, with the
body being the list text. The headers of the block could
house additional parameters and styling options.

e.g:

«code | lang : gdtxt ;
\« list | type : ordered | page-break: keep-together ;
• How/when are they terminated?
• How do you control numbering styling?
• Should a list be split across pages?
\»
»

• This make's it easy to change between numbered
and bullet lists.
• checkbox would still be determined by adding [\[\]]
next to the [•].
• parser is simplified as it's a block with a special handler
for the body?

Cons of this approach:

• arguably harder to read.
• more to type
