Subject: [RFC][BUG] IO::Notification needs .stat and seperate notification for removal
Download (untitled) / with headers

Two scenarios will render the following code "useless".

my $p =; 'a' ).act: { .event.say; }
await $p;

1. If file or directory 'a' does not exist, no Failure.
2. If 'a' initially exists, then removed/moved, then a new 'a' is created, the new 'a' no longer has the identity of the initial file/dir that was 'a'. Subsequent behavior is same as that of 1.

Lacking a .stat method, and a way of notifying removal, there isn't a good way to track the original target, and figure out nature of the change.
