<pre>Unfortunately the following code fails to compile (using the STL of g++-10.2):
==== begin test program ====
#include <ranges>
#include <array>
std::array<int,2> points_;
auto foo() {
auto v = std::views::transform([](int p) {return p;});
return points_ | v;
}
int main() {
auto z = foo();
}
==== end test program ====
The same code compiles without problems using g++-10.2 so I think it should be
valid code...
