That's one of the things the prototype does. If you specify (\@) then passing an array func1(@arr) is correct. Passing func1(\@arr) would actually fail the prototype check (as would suppling a list instead of an array). ikegami had to pass a reference because the prototype was removed.

Update: my reply overlapped with that of ikegami
