Subject: Re: [PHP-DEV] RFC Proposal - Attributes read/write visibility

My point is not to add two ways to do the same thing.
What I'm humbly suggesting to do is to keep the core idea of the existing
RFC (make things easier when you have to write getters/setters), and think
about another syntax for managing reading and writing visibilities.
