Anyway, I highly respect the ConTeXt and LuaTeX's work. But if Taco and Hans can :
- use a proper regexp library (like lrexlib?), not the silly lpeg
PEG are not silly at all. PEG *include* regex, but not viceversa, and it seems to have the same power of CFG, so you can build a parser for pratically anything (and you can not do this with regex) . Perhaps the reverse sentence has more sense: drop the "silly" (?) regex, use the new peg. For what I know the reverse side of lpeg is that a file must be loaded in memory completly. - more powerful multi columns (maybe not through gird typesetting?)
Maybe columnset can do more, or we need more examples from hans . - full support of xslt:)
why not xquery too? Are mkiv supposed to be a full xml processor ? A bit of xslt can be done with lpeg (and not regex), but usually it's better to prepare a xml to typeset before processing with mkiv ("use the right tool for the right task").
Things might be a lot better...
and worse too . Things are now a lot better than before ,IMMO . -- luigi
