Instead of re-blessing, you should ...

I never said one should rebless. My meditation illustrates a technique using inheritance tree twiddling, not reblessing. But TIMTWOTDI. I mentioned re-blessing parenthetically because it's another way to achieve the same result, and might be preferable for some people or in some circumstances.

What you call strategy is the View in Module-View-Controller pattern.

Only in the example I gave. Strategies can be used anywhere in an architecture.
