Ok, fair enough. I would instead say "think in terms of entities of the
problem domain", however. One can implement the catalog of goods using a
hash-table, but for the implementor of the hash-table service, the problem
domain becomes indeed "wizard" concepts. 

I don't see any reason why a certain class of abstractions (i.e. programming
ones) is not appropriate for OO conceptualization just like any other. The
real point is to use the appropriate abstractions for the domain.
