Bug ID: 102301
Summary: make_from_tuple can not work with subrange
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: hewillk at gmail dot com
Target Milestone: ---
I don't know if it is a bug, because the standard does not specify whether
make_from_tuple can be applied to subrange even if it looks well-formed, so
this may only be regarded as a feature request.
Given that MSVC-STL already supports it, I think it should have some value.
#include <ranges>
#include <vector>
int main() {
auto v =
std::make_from_tuple<std::vector<int>>(std::ranges::subrange(std::views::iota(0,
5)));
}
