I would not be at all reluctant to write production code that reblesses objects.

I wouldn't even consider doing so unless a good chunk of the component was designed around that idea. But if, for instance, a good chunk of my system was a "state diagram" with the current state indicated by the current class, then I would be perfectly willing to proceed.

In the abstract I think that would be perfectly maintainable. Certainly it is a design pattern that fits with a circle of ideas which I know are both natural and maintainable for certain classes of problems. The practical implementation may be a different matter, but my sense is not against it.

That said, I have never actually needed that design. Nor would I encourage casually experimenting with it in production code just to see how it works - most times it would be a horrible fit for sanity and in this case I would definitely go with your proxy idea.

But still, unless the concept of "state transitions" is utterly essential to how you are thinking about your functioning system, I wouldn't rebless.
