.... or something like that.
I have an XMLish data structure whose nodes' __get/set/del item__
methods resolve as:
node['foo'] -> node.children['foo']
node['@bar'] -> node.attributes['bar']
so you can say:
countries['us']['Colorado']['Denver']['@population']
This is going to be used in user-input formulae, so I'm willing to do a
lot of work for minor beautifications. I'd like to be able to say (I
know, the quotes are still ugly, but at least you save a bracket):
countries/'us'/'Colorado'/'Denver'/'@population'
That's easy to do with a __div__ method, but it only works for getting,
not setting or deleting.
I'd appreciate any thoughts on this problem. I keep thinking
descriptors might be involved somehow in the solution, but I may be on
a completely wrong track.
