constexpr inline auto tl::pipeable
template<class F>
constexpr auto operator()(F f) const

Makes the given function pipeable to other functions and pipeable from ranges.

range | pipeable(f); // equivalent to f(range)
pipeable(f1) | pipeable(f2); // equivalent to compose(f2, f1)

All range views in the tl namespace are already pipeable. This function is useful for adapting views from other libraries or the standard library. E.g.:

auto enumerate_reverse = tl::views::enumerate | tl::pipeable(std::views::reverse);
for (auto e : my_vec | enumerate_reverse) {
