Description

(Filing this mostly as a reminder after taking a quick look at the code)

A bunch of places materialize Python lists of tokens unnecessarily (by calling list() on some iterable).

This isn't a huge deal as we likely will never really need to deal with giant schemas, but it's unnecessary.
We should instead only do this if/when we ever need to (e.g. to maintain state for our additional parsing).

Research direction

The issue names no files or tests. Start by locating the places where token iterables are wrapped in list() and determine which materializations are unnecessary; done means those lists are no longer created unless needed for parser state, without changing lexer behavior.
