I would find it nice if better design options could gain acceptance.
Will the chances grow to adjust scopes another bit for involved variables
in such function implementations?

A) Enclosing a source code part with extra curly brackets?

B) scoped_guard()?

C) Moving a locked source code part into a separate function implementation?
