EVERY_SINGLE_PARENT_METHOD =

this is super-lame i can’t find a way to intercept instance var access and the REXML Parent class does not provide an initialization hook so we basically have to wrap each and every method (well, at least the ones that interact with the @children var), in order to be able to invoke an initialization method either the design of the Parent class sucks, or I’m just missing some great idiomatic way to do this
