I prefer the arrow operator since it provides a nice, overt dereferencing visual suggesting it's pointing or referring to something else.

    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.)


      When your only tool is a hammer, all problems look like your thumb.
