I’ve been thinking about the change made 2-3 years ago where it’s
no longer permitted to set variables inside a case statement (or similar).
Is it fair to summarize this by saying: Variable values can pass from an
outer context to a more inner one, but those variables cannot be bound
to new values (such that the outer context changes)?
This afaik applies to any “block” of code nested inside a larger context –
the “guts” of an if, case, cond, code passed to a macro…
Am I looking at this correctly or not?
