i think the line is "would you rather have ten equally broken ways to do it,
or two reasonable ways?"

tie method invocation involves marshaling, and nearly all gtk2-perl functions
involve marshaling.  the tied stuff compounds that.

if we go to using accessor methods to get data in and out of the tree at
paths, then the tie is, well, pretty much unnecessary.  a list of lists
structure could be used to represent the data when going in and possibly
dumping out.
