Jeff Eastman commented on MAHOUT-65:
------------------------------------
This thread is beginning to diverge significantly from its original problem
statement. While I can understand the trade-offs between binding optional Label
maps to every Vector/Matrix instance vs. creating a new wrapper type to add
labelled accessing when needed (Wettin 14-Jul) the above proposal seems to
combine the worst of both worlds. I'd sure like to understand the problem we
are trying to solve before going further. In particular, I do not understand
the generality or universal utility of the specific attributes that are being
discussed.
Karl, could you please state the problem you are trying to solve and how
closely binding these Attributes to every Vector/Matrix instance helps us to
solve it?
