I can't. I have never written code in a language which has such a
module system. I read about these module systems decades ago.
For more details, or examples, you will need to ask people who have
actually used them.

What I recall is NOT that there are "different visibility rules",
but rather that the visibility rules would apply to specific definitions.
Perhaps in those languages a given symbol can have only one active
definition in any scope. So a symbol could be have a function definition
or a variable definition in any given module, but never both.
I think that is the situation in Scheme. But I have never programmed
in Scheme.

Perhaps "shadow" or "shadowing-import" amount to the construct I was
envisioning. I saw those terms only today, and I don't know what they
mean.

It could be made upward-compatible, but not fully compatible: programs
using :INHERIT would not load in standard Common Lisp.
