Whereas '__iter' would be taking this historical evolution to its logical

Generic For undoubtedly was a significant complication of the language, much
more significant than "__iter" would be.

But I would be interested to understand the reasoning behind implementing
Generic For as it seems to be subject to the same criticisms you are now
levelling at "__iter" - the old way was simpler and required no language
innovations, so why was it deprecated?

I am in two minds between table.foreach and Generic For with __iter, but I
find Generic For without __iter to be a rather half-assed implementation!

Yes, it would be reversing the historical evolution of the language.
These functions are easy to define efficiently anyway.
