--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
lambda is AFAIK a local class, so you need to instantiate it. So it is more
similar to:
#include <type_traits>
template<typename T>
constexpr bool run() { return false; }
template<typename T>
T get() {
struct S {};
if constexpr (std::is_same_v<int, T>) return 0;
else static_assert(run <S> (), "Lambda expression is evaluated.");
}
int main() {
get<int>();
}
which also compiles fine (and doesn't compile if you use say int or something
non-dependent in run template-id).
