i disagree. if you want complex tree results, use a rule. split is for
creating a single list of elements from a string. it is better keep
split simple for it is commonly used in this domain. tree results are
more for real parsing (which split is not intended to do) so use a
parsing rule for that.
also note the coding style rule (i think randal created it) which is to
use split when you want to throw things away (the delimiters) and m//
when you want to keep thinks.
