AFAIK this feature has been in C++20 and implemented.

[C++] clang 14.0.0 - Wandbox<https://wandbox.org/permlink/odPnEY4bOxTbKtx3>

主题: [std-proposals] Allow usage "consteval" in lambda-functions

Hi everyone!
I suggest allowing the use of "consteval" in lambda functions as well
as the use of "constexpr" in C++20.

=== EXAMPLE ===
// ...
const int x = 3;
auto lambda = [=]()
    consteval -> int
        return 1<<x;
std::cout << lambda();
// ...

Best regards,
