And if you don't have an argument to pass, isn't it weird to have empty parenthesis?


There are no stupid questions, but there are a lot of inquisitive idiots.

    Why would it be weird? Parens around the arg list, even an empty args list, is the normal way of calling a sub. Omitting parens leads to many problems.

    As a long-time C/C++/C# coder, I don't find the empty parenthesis weird. (Though it took me a (very) little while getting used to leaving off parenthesis altogether.)
