Range access function templates (25.7 [iterator.range]) are available in every standard header for containers. As std::basic_stacktrace provides some container-like interfaces (member functions begin, end, size, etc.), should we add these free function templates to <stacktrace> for consistency?

This wording is relative to N4901.
[Drafting note: The proposed wording below contains one conditional change, it is therefore depending upon a decision]
Modify 25.7 [iterator.range] as indicated:
-1- In addition to being available via inclusion of the <iterator> header, the function templates in 25.7 [iterator.range] are available when any of the following headers are included: <array> (24.3.2 [array.syn]), <deque> (24.3.3 [deque.syn]), <forward_list> (24.3.4 [forward.list.syn]), <list> (24.3.5 [list.syn]), <map> (24.4.2 [associative.map.syn]), <regex> (32.3 [re.syn]), <set> (24.4.3 [associative.set.syn]), <span> (18.104.22.168 [span.syn]), <string> (23.4.2 [string.syn]), <string_view> (23.3.2 [string.view.synop]), <unordered_map> (24.5.2 [unord.map.syn]), <unordered_set> (24.5.3 [unord.set.syn]), and <vector> (24.3.6 [vector.syn]). […]
If we decide that <initializer_list> should be included if the header has dependency on std::initializer_list (it may be introduce by std::rbegin, std::data, etc.), #include <initializer_list> should also be added to 19.6.2 [stacktrace.syn].
