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 \scantokens \everyeof \endlinechar with proposals l3toks: \toks_rescan:n l3io: \l_ior_eof_toks 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? Will
