When we encounter a binder like for<..> fn(..)
, we actually have
to walk the fn
value to find all the values bound by the for
(these are not explicitly present in the ty representation right
now). This visitor handles that: it descends the type, tracking
binder depth, and finds late-bound regions targeting the
for<..
>. For each of those, it creates an entry in
bound_region_scope
.
