There is no stl concept for pointer, maybe I can create one for the xtl and use it.

You can shorten the declaration with:
template <std::convertible_to<T> S>
operator xrange<S>() const noexcept;Here S will be passed as the first argument of the concept used in the type constraint.

This should be snake_case ;)

You can use std::is_signed_v

Description
This PR C++20's concept and C++17's if constexpr to a moderatly large chunk of xtensor.
