Headings add exit matcher for heading
Paragraphs add exit matcher for elements (but it should be sans paragraph)
* foo
* bar
* baz
context tree -> ()
match * foo
context tree -> exit(heading matcher)
check exit
invoke heading matcher
check exit
invoke heading matcher
check exit
invoke heading matcher
adds second heading matcher exit
Ways around this:
- Always parse SOMETHING before checking for exit
- Doesn't always seem possible
- Disable exit matchers during exit check
- Seems like it would break syntax
- Have separate parsers for the beginning of the exit condition (for example, checking for just the headline instead of the full heading parser)
- Won't be possible with paragraphs ending at any other element
- Check exit matchers in parent parser
- Will this work? seems like it would just create larger loops
