I interpret it that as that you are telling me that *you* introduced
"subtle bugs". (Okay, we know you, so that is not too surprising. But
I rather suspect you are just saying that just to make an argument.)

That is the point of shadowing! If you introduce a new name in an
embedded local context you do so to want to refer to that. That's
the whole point of shadowing that you don't get errors but can use
a local name instance without interference and without destroying
a "global" value of the same name.

Would you prefer a language without hierarchical blocks, scopes,
and shadowing?! (rhetoric)

This is obviously your personal problem; operating on something you
haven't declared is not a problem of shadowing.

Shadowing is a sensible, useful, and safe concept that appeared with
block structured, stack oriented languages (I think with Algol 60),
and which had been inherited for good reasons to most (if not all)
subsequently appearing languages that support blocks and local scopes.

That is something completely different; you are shifting the goalpost!
(I won't explain you the PATH concept here, or why it is very useful.
And some things have already been explained elsethread by Scott.)
