In dev's A05.html I only found: "[Update: That must now be written <+<alpha>+<digit>>, or it will be mistaken for «alpha><digit», which doesn't work too well.]". I see those character classes as infinite sort-of-binary masks, so <alpha|digit> looks right to me. Idem <[_] | alpha | digit & !Swedish>, with left-to-right application. (I don't oversee the consequences.) -- Grtz, Ruud (sober.u is on the loose)
