Indicates that cmt
is being directly mutated (e.g., assigned
to). If cmt contains any by-ref upvars, this implies that
those upvars must be borrowed using an &mut
borrow.

We infer the borrow_kind with which to borrow upvars in a stack closure.
The borrow_kind basically follows a lattice of imm < unique-imm < mut
,
moving from left to right as needed (but never right to left).
Here the argument mutbl
is the borrow_kind that is required by
some particular use.
