Easily currying functions in C++
1// Existing, non-curried function
2auto f(int a, int b, int c) noexcept -> int {
3 return a * b * c;
4}
5
6auto g = fn::curry(f); // g is the curried form of f
7
8int main() {
9 return g(2)(5)(10); // returns 100

Fold expressions work inside constraints
1template <template <typename> class FooT, typename... T>
2requires (... && Bar<FooT<T>>) struct Baz {};
Without fold expressions:
1template <template <typename> class FooT, typename... T>
2requires([]() {
3 std::array arr = std::array{Bar<FooT<T>>...};
4 return std::reduce(arr.begin(), arr.end(), true, std::logical_and<bool>{});
5}()) struct Baz {};
consteval-huffman
A C++20 utility for compressing string literals at compile-time to save program space. The compressed data can be decompressed at run-time through the use of a decoder that follows std::forward_iterator.
1auto data = "This is my string of data"_huffman;
