It's simple:

You can omit the "()" at the end of function call statement only. It's a 
compiler shortcut that comes from Visual Basic.

I said "statement", not "procedure", because the interpreter makes no 
difference between a procedure (that returns nothing) and a function 
(that returns something) in the sense that it discovers that behaviour 
at runtime during the execution ; contrary to you, that knows that in 
advance.
