that was one of the two ways i thought about doing it, well with the
values first and then the children, but same difference. basically my
reasons against it where it makes for unreadable code:

@{$stree->{data}[12][1][3][1][2][0]} = [...];

if you're new at things and you see that you're likely to run away
screaming. whereas 

@{$stree->{data}[12]{children}[3]{children}[2]{values}} = [...]

might be more verbose, but it's nearly self documenting, 13th element's
4th child's 3rd child ... by far the most common case (especially with
SimpleTree) is a two level list. categories and members of those
categories. in that situation the hash version doesn't get too ulgy.

i don't disagree about the hash form being pretty verbose, but i guess i
think the verbosity is worth it. i guess we could make both versions if
there were enough people who felt strongly enough about it, but i'd
really rather not.

cool.
