 There is also a method to schedule an operation to run after a certain time
 period:
 
-    $*SCHEDULER.schedule_in({ say "10s later" }, 10);
+    $*SCHEDULER.schedule-in({ say "10s later" }, 10);
 
 And one to schedule an operation to run at a fixed interval, possibly with a
 delay before the first scheduling.

 [To consider: we could have a single schedule method taking named parameters
 :$catch, :$in, and :$every instead.]
