 NativeCall also supports native functions that take functions as arguments.  One
 example of this is using function pointers as callbacks in an event-driven
-system.  When binding these functions via NativeCall, one should need only provide the
-equivalent signature as L<a constraint on the code parameter|/type/Signature#Constraining_signatures_of_Callables>:
-
-    # See below--this syntax does not work on Rakudo currently
-    use NativeCall;
-    # void SetCallback(int (*callback)(const char *))
-    my sub SetCallback(&callback:(Str --> int32)) is native('mylib') { * }

 literal is ommitted, as in:
