<stacktrace> provide range access function templates?Section: 19.6.2 [stacktrace.syn], 24.7 [iterator.range] Status: New Submitter: Jiang An Opened: 2021-10-23 Last modified: 2022-01-29

Discussion:
Range access function templates (24.7 [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 issue is related to LWG 3624.

Set priority to 3 after reflector poll.
Proposed resolution:
This wording is relative to N4901.
[Drafting note: The proposed wording below contains one conditional change, it is therefore depending upon a decision]
Modify 24.7 [iterator.range] as indicated:
-1- In addition to being available via inclusion of the
<iterator>header, the function templates in 24.7 [iterator.range] are available when any of the following headers are included:<array>(23.3.2 [array.syn]),<deque>(23.3.4 [deque.syn]),<forward_list>(23.3.6 [forward.list.syn]),<list>(23.3.8 [list.syn]),<map>(23.4.2 [associative.map.syn]),<regex>(28.6.3 [re.syn]),<set>(23.4.5 [associative.set.syn]),<span>(23.7.2.1 [span.syn]),<stacktrace>(19.6.2 [stacktrace.syn]),<string>(27.4.2 [string.syn]),<string_view>(27.3.2 [string.view.synop]),<unordered_map>(23.5.2 [unord.map.syn]),<unordered_set>(23.5.5 [unord.set.syn]), and<vector>(23.3.10 [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].
