+// This class is an *almost* drop-in replacement for std::function which is guaranteed to never
+// allocate, and always holds the type erased functional object in an in-line small buffer of
+// templated size. If the object is too large to hold, the type will fail to instantiate.
+//
+// Some notable differences are:
+// - operator() is not const (unlike std::function where the call operator is
+// const even if the erased type is not const callable). This retains const
+// correctness by default. A workaround is keeping InPlaceFunction mutable.
+// - Moving from an InPlaceFunction leaves the object in a valid state (operator
+// bool remains true), similar to std::optional/std::variant.
+// Calls to the object are still defined (and are equivalent
+// to calling the underlying type after it has been moved from). To opt-out
+// (and/or ensure safety), clearing the object is recommended:
+//      func1 = std::move(func2); // func2 still valid (and moved-from) after this line
+//      func2 = nullptr; // calling func2 will now abort
+// - Unsafe implicit conversions of the return value to a reference type are
+// prohibited due to the risk of dangling references (some of this safety was
+// added to std::function in c++23). Only converting a reference to a reference to base class is
+// permitted:
+//      std::function<Base&()> = []() -> Derived& {...}
+// - Some (current libc++ implementation) implementations of std::function
+// incorrectly fail to handle returning non-moveable types which is valid given
+// mandatory copy elision.
+//
+// Additionally, the stored functional will use the typical rules of overload
+// resolution to disambiguate the correct call, except, the target class will
+// always be implicitly a non-const lvalue when called. If a different overload
+// is preferred, wrapping the target class in a lambda with explicit casts is
+// recommended (or using inheritance, mixins or CRTP). This avoids the
+// complexity of utilizing abonimable function types as template params.
