GB301 24.07.4.2 Add filter_view::pred() accessor P1983 #297
Description
filter_view has no pred() member
Other views taking predicates (take_while_view and drop_while_view) have a pred() member returning (a const reference to) the contained predicate object, but filter_view does not
Proposed change:
In [range.filter.view], add
constexpr const Pred& pred() const;
Effects: Equivalent to: return *pred_;
