just repeating my previous idea - what about `extends` for functions? eg:
package Foo {
sub SEARCH (... signature ...);
}
sub function :extends(&Foo::SEARCH) { ... }
later extended signature support for setting fixed value (in opposite to
default value) of parameter, eg:
sub function :extends(&Foo::SEARCH) ($search_key := value = q (fixed
value)) { ... }
