Coding standards

Is there a reason for us not to make disinction between static and entity methods and between private and public methods? I find it very hard to look through the code to figure out which methods I can call when subclassing or using objects or using classes. I've always used capitals on static methods and underscore on private. Thus: function foo() -- public entity method function _foo() -- private entity method function Foo() -- public static method function _Foo() -- private static method Even though php of now isn't case-sensitive when it comes to functions (which it will be in the future (4.1?)) it would make much more sense. /erik hjortsberg
