| Thanks.

No, but I don't have at the moment an exhaustive list of concerns that
I would be keepigng to myself :-).
However, I hope that people with more interests in this style of
programming will come up with a coherent, reasonably complete,
proposal that I could study and hopefully influence my preference.
I know of programming languages (and have written programs in such
languages) that allow similar form of overloading. I was never
impressed. That may change; but I suspect that would require more
extensive realistic examples and explanation of why it would be good
for me to abandon my unsophisticated world of non-overloaded variables.
