pow wrong???

4

Building with Clang 9.0.1 on Manjaro Linux, I'm getting the result that `sprout::pow(8, 4)` is equal to 4095 instead of 4096. Am I dumb, or is there a problem here?...

Does someone still have access to this repository?

Hello all. This is a grim issue indeed. Unfortunately, Bolero Murakami passed away in February of this year. Since repository access is not publicly visible, does someone still have access...

`std::is_literal_type` was deprecated in C++17 and removed in C++20. [Section [diff.cpp17.depr]/7](https://eel.is/c++draft/diff.cpp17.depr#7) of the C++20 Working Draft explains: > The traits had unreliable or awkward interfaces. The `is_­literal_­type` trait provided no...

sprout::enabler の定義が無い

4

[`sprout::enabler_if`](https://github.com/bolero-MURAKAMI/Sprout/blob/master/sprout/type_traits/enabler_if.hpp#L31) を使用する場合は以下のような感じになるので、[`sprout::enabler`](https://github.com/bolero-MURAKAMI/Sprout/blob/master/sprout/type_traits/enabler_if.hpp#L25) は ODR-used になると思うのですが、[`sprout::enabler`](https://github.com/bolero-MURAKAMI/Sprout/blob/master/sprout/type_traits/enabler_if.hpp#L25) は GCC や clang では定義されません。 ``` cpp #include template void f() {} int main() { f(); } ``` ODR-used のオブジェクトが定義されていないと ill-formed になるので（ただし、no diagnostic required）、GCC や...

[sprout/config/compiler/visualc.hpp](https://github.com/bolero-MURAKAMI/Sprout/blob/844e8a1fc29ab72e27b5165f92c0762177afd096/sprout/config/compiler/visualc.hpp) で現状`constexpr`と`noexcept`が無効化されていますが、`noexcept`はVIsual Studio 2013 November CTPから、C++11の`constexpr`はVisual Studio 2015から対応しているように思います。ついでにC++11の他の機能への対応をまとめると - Visual Studio 2015より対応 - C++11constexpr - User-defined literals - Unicode string literals - VIsual Studio 2013 November CTPより対応 - classのdefault指定 -...

https://github.com/bolero-MURAKAMI/Sprout/blob/master/sprout/variant/variant.hpp shows, on lines 81 and then on lines 52 and 40 that the size of the variant is sizeof(int)+sizeof(tuple. That seems a waste of space to me since other...
