Hi Joseph and others,
Sorry to have to ask this but I was a bit disorganised last year... a
few primitives have been brought up that don't have proper interfaces
in expl3 yet. I left myself a note to look at this but neglected to
write down which ones were actually missing!
At the moment I've got
l3token: \l_char_end_line_int (?)
(All from a thread last year on the same topic.)
Do you happen to remember if there are any others?
