shouldn't include be _include?

[naturallymitchell]

or is the difference you have planned between an assignment and a special vocab term is that an assignment has an "="?

because right now, we can have fields called "include", but they'll kinda clash with the special namespace. it's a bit ambiguous.

it'd make more sense to me to have the special namespace start with an underscore either way.

this would also help if you decide to go with meh's suggestion in #3
