in thread Dots and cargo-cult programming

Not to be pedantic, but where I come from (c++) -> *is* the standard way to call functions that live inside an object that you have a pointer to, which is pretty much the only way I ever use it in perl too. (blessed ref to an object)

    Several of the differences between Perl5 and Perl6 are intended to reduce the amount of dereferencing you have to do. So I like thinking of this syntax change as just being Yet Another way of indicating to people that you are supposed to be thinking in terms of more immediate data structures and less about having a reference that you dereference.

    YMMV, but that is true to the usage of both . and -> in C.

      I'm not sure I follow this. The dot is ugly, but it's not like it inherently discourages you from using it. In fact, it could be said "->" is better for that purpose: more letters to type. (And 3 times more keys!) Plus, you have to use it for objects, unless you want to encourage 'indirect object' syntax.

      -- Frag.

        In C accessing a struct directly is done with a ".", but accessing a struct through a reference is done with an "->". So to my eyes the arrow says "indirected through a reference.

    Well I'm glad somebody pointed this out.

    It isn't to emulate Java, VB or SmallTalk so much as to make the code cleaner and easier to parse. Admittedly I'm attached to the existing arrow operator but I can get used to using a dot instead.

    There are more important battles to fight. That's such a minor one.
