Calling a function with empty parens, `dostuff()`, passes an empty parameter list. The `@_` array in the called function will be empty. Of course, by putting parameters in the parens, you will pass them. Calling a function with the ampersand, `&dostuff`, will pass the current contents of `@_` to the called sub. This can be very useful for exception handling, OO programming, or perhaps if you rename a function but want to keep the old function around because others are still using your code.
