Hi Taco, though luatex isn't frozen yet, I think that many people are using it already and drastic changes are not desirable.
There is one thing which could probably be improved without breaking existing scripts, as far as I can see:
string.explode(foo, ' +')
expects that ' ' is a space token (ASCII 0x20). Is it possible to change string.explode() so that ' ' can be either a space token (ASCII 0x20) or a tabulator (ASCII 0x09) without breaking existing scripts?
By definition, this would break those scripts that use string.explode() expecting spaces aren't tabs. Personally, I wouldn't mind if the function was modified in order to understand regular expressions, although that would quite clearly be incompatible with previous behavior. Best, Paul
