The ampersand in front of the subroutine name is a very specific feature which can get you in trouble if you're not expecting it. &someSub != someSub();
If you prefix a subname with an ampersand that sub will be called with the current contents of @_, unless you explicitly state the contents. Consider: That code happily prints "Hi, there!" (without the quotes), despite an apparent lack of arguments in the sub2 call.
