The dot notation is used for at least two different purposes: accessing field values (C structures, for example) and calling methods on/sending messages to an object (Java, for example). Similarly the arrow notation is used for at least two different purposes: accessing field values through a pointer (pointers to C structures, for example) and calling methods on/sending messages to an object (Perl, for example).
Standard? I don't think so. They are used for very different purposes, and just because the convention of separating a record or an object and its attribute with a dot or an arrow is common is not reason enough to blindly adopt the same convention in a new programming language.
Does the dot notation as a record and field separator make sense? Maybe, if that's all you can do in your programming language. Take a look at Common Lisp defstruct for an example of another way to define structures and access fields.
