Subject: Re: [PHP-DEV] [RFC Discussion] Typed Properties

Morning Dmitry,

    So, I quickly reviewed the RFC and patch.

    Static properties, and mixed declarations, are now explained in the RFC.

    I made a couple of changes to the fetch_obj_w stuff, I'd be grateful if
you could review that ... I didn't think I had got all possible
combinations, should be bit better, and drier ...

    The overflow related stuff, I'll fix and explain in the RFC, but I'll
let you have a go at perf stuff, and other outstanding things now ...

    */me leaves patch alone*

Cheers
Joe
