Makes me think about parallel operations.
for 0...10 -> $x { ... } # 0 through 10 in order
for 0..10 -> $x { ... } # Spawn 11 threads, $x=0 through 10 concurrently
for 10..0 -> $x { ... } # A no-op
for 10...0 -> $x { ... } # 10 down to 0 in order
though would a parallel batch of an anonymous block be more naturally written as
all(0...10) -> $x { ... } # Spawn 11 threads
-y
