+// `absl::bind_back()` returns a functor by binding a number of arguments to
+// the back of a provided (usually more generic) functor. Unlike `std::bind`,
+// it does not require the use of argument placeholders. The simpler syntax of
+// `absl::bind_back()` allows you to avoid known misuses with `std::bind()`.
+//
+// `absl::bind_back()` is meant as a drop-in replacement for C++23's
+// `std::bind_back()`, which similarly resolves these issues with
+// `std::bind()`. Both `bind_back()` alternatives, unlike `std::bind()`, allow
+// partial function application. (See
+// https://en.wikipedia.org/wiki/Partial_application).
