I believe it's official syntax. It's not (quite) documented in the developer
documentation, but I assume it's in the clang docs somewhere. Here's an actual
line of code, as a more familiar example:
NSIndexSet* selectedIndexes = [listView.selectedRowIndexes
indexesPassingTest: ^BOOL (NSUInteger rowIndex, BOOL* stop) {…}
I'm not sure it's worth letting the compiler figure out the return type, and
casting is always a potential bug because it always suppresses a compile time
type check.
