36    Some tokens cannot be created yet because they are more complex but eventually the creator will
37    deal with them. The indices are sometimes the same as internal but in most cases nicely start
38    at zero. When they start at another value, then there is an internal token or state that is not
39    user accessible. You always need to use symbolic constants as the numbers can change.
40
41    The first column is a classifier (which is experimental and categories might change when we feel
42    the need).

60    Here is a typeset table of \type {\startframed} using \type {\luatokentable\startframed}:
61
62    \luatokentable\startframed
63
64    which calls \type {\pack_framed_start_framed} where \type {\luatokentable\pack_framed_start_framed} gives:
65
66
67    \unprotect
68    \luatokentable\pack_framed_start_framed
69    \protect
70
71    So you can guess what generates this:
72
73    \unprotect
74    \luatokentable\pack_framed_start_framed_nop
75    \protect
76
77    And this:

79    \unprotect
80    \luatokentable\pack_framed_start_framed_yes
