 Flattens the array C<@args> according to the prototype C<$proto>.
 When C<@args> is what C<@_> is after calling a subroutine with prototype C<$proto>, C<flatten> returns the list of what C<@_> would have been if there were no prototype.

 Generates a wrapper that calls the function C<$name> with a prototyped argument list.
 That is, the wrapper's arguments should be what C<@_> is when you define a subroutine with the same prototype as C<$name>.
