dict vs coll

chase's icon

Is there an explanation or discussion available anywhere of how dict is supposed to relate to, replace, or extend coll? There's a mention elsewhere on this forum that "the future is dict"

...which seems to indicate that dict is intended at least partly as a replacement for coll with its decades of baggage - but I can find no further information on the relationship or how to use it (the "coll" tab in the "dict.maxhelp" does not qualify).
