Sorry for putting too much emphasis on the "forced", that wasn't my 
intention. I was mentioning that often simple problems appeared more 
complex because the person was thinking in a higher level data structure 
than is necessary. "forced" in that sentence means to let people to 
think a little bit harder with list/dict before deciding that they are 
unsuitable and moving to a tree or a graph.
