in thread Accessing a scalar value in another subroutine?

Yes. I read the docs; but would still like to a see an example of actual, practical use.

The only example I've seen that makes any logical sense at all (to me), is the ability to query the information in a repl.

But that extremely limited-use facility, does not justify burdening the runtime with the overheads it imposes, in a language who's runtime has facilities designed to support it.

Emulating that limited-use facility in a language the does not have runtime facilities to support just imposes addition runtime costs for no conceivable benefits.
