I would propose another radical solution for this: Simply that shadowing
variables is not allowed.
Good bye block scoping.variables is not allowed.

When you are about to shadow a variable, use a
different variable name.
I mean this really serious; compared to C, Go made some useful
restrictions,
limiting the programmer's freedom in some way, like the mandatory use of { }
in all if's anf for's. Forbidding variable shadowing could be one more such
thing. I could live with that restriction very well.I cannot recall a single one of the imperative mainstream languages
which doesn't have block scoping. Not an argument, of course. Just
makes one wonder why it is like that.
