// yes, deliberately import this category header after the declarations above
// it depends on JPHAsyncOpBlock to be defined but when imported by this file,
// its own import of this same header is of course short-circuited.
// could instead have JPHAsyncOperation/JPHAsyncOperation.h be an umbrealla header
// which includes this and then the category header.
