template <typename Callable>Callable * target (bool check)Returns a pointer to the function's target.
If |check| is true (the default), the function _may_ abort if the
caller tries to assign the target to a varible of the wrong type. (This
check is currently skipped for share()d objects.)
Note the shared pointer vtable must set |check| to false to assign the
target to |void*|.

template <typename Callable>const Callable * target (bool check)Returns a pointer to the function's target (const version).
If |check| is true (the default), the function _may_ abort if the
caller tries to assign the target to a varible of the wrong type. (This
check is currently skipped for share()d objects.)
Note the shared pointer vtable must set |check| to false to assign the
target to |void*|.

template <typename SharedFunction>void share_with (SharedFunction & copy)Used by the derived "impl" classes to implement share().
The caller creates a new object of the same type as itself, and passes in
the empty object. This function first checks if |this| is already shared,
and if not, creates a new version of itself containing a |std::shared_ptr|
to its original self, and updates |ops_| to the vtable for the shared
version.
Then it copies its |shared_ptr| to the |bits_| of the given |copy|, and
assigns the same shared pointer vtable to the copy's |ops_|.
The target itself is not copied; it is moved to the heap and its lifetime
is extended until all references have been released.
Note: This method is not supported on |fit::inline_function
<
>|
because it may incur a heap allocation which is contrary to
the stated purpose of |fit::inline_function
<
>|.

Result invoke (Args... args)Used by derived "impl" classes to implement operator()().
Invokes the function's target.
Note that fit::callback will release the target immediately after
invoke() (also affecting any share()d copies).
Aborts if the function's target is empty.

template <typename Callable, typename = std::enable_if_t<std::is_convertible<
decltype(std::declval<Callable&>()(std::declval<Args>()...)), result_type>::value>>void assign_callable (Callable && target)Used by derived "impl" classes to implement operator=().
Assigns the function's target.
If target == nullptr, assigns an empty target.
