perhaps we could extend namedtuple to become the "frozenDict"

aren't they database? Am I missing something here?

if it were to happen, it would take python 4 or python 5 and the idea's 
runner must beat Guido down from his throne first... I think... not that 
they weren't a good idea... and other python implementations might want 
their own namespace as well to contain implementation specific modules 
(imagine "ipy", "cy", "us", "aspn", etc popping up here and there).
