r"""
Represents a ly.lex.State as a simplified list of strings.

    \book {
      \header {
        title = \markup { #"

e.g. yields:

    ['lilypond', 'book', 'header', 'markup', 'scheme', 'string']

This is done by examining the state's parsers.
It can be used in snippets or plugin scripts.

The first word is always the mode of the file (e.g. 'lilypond', 'html', etc.).
