If I understand you correctly, a new kind of qualifier for
`line` may be motivated here. The semantic meaning of `scope` D
is not related to volatile property. I guess the problem is
somewhat related to reference counting and ownership, right.
See my other reply. Originally I thought so too, but it turns out
they can't really be separated. It's basically an instance of
Rust's restriction "exactly one mutable reference, or N immutable
references, but not both at the same time".
