Reuse is a matter of perspective. During the OO marketing blitz of the 90's, promise of re-use (C++, etc etc) convinced many to jump in the pool. So today there is a tremendous amount of abstract and deep hierarchies build with the notions that: "Someday this may be useful to specialize from this Class thereby enabling 're-use'" ... *BS!!!! There is much more code that does NOTHING in the hierarchy other than putting a drag on the timeliness of delivery.*
True reuse emerged at the macro level (i.e.Module orientation, Re-provisionable services, Web Services, etc.) while the micro level adventure leaving bloated unmaintainable artifacts in it's wake. The fundamental essence of functional approach has done more for reuse at the micro level then all OO languages combined. IMHO.
