Can we introduce WeakPtrWillBeMember?

[sof, 2014/06/02 07:20:06]

I considered it too specialized & a one-off occurrence, but perhaps it is worth
doing so?

[haraken, 2014/06/02 07:26:47]

Either is fine, but I might to use it in modules/websocket :)

[sof, 2014/06/02 07:31:04]

Thanks, let's add it here then :)
