I have to agree with Richard as a user-land developer. It looks nice, but
knowing how people can twist things I don't think I would like this feature
get implemented. It just add stuff that is crazy to debug.
Consider someone adds a property and initializes a user-land object. That
object has other object properties with are created and the chain goes on
for 2-3 more levels. Dealing with a __construct or a dedicated init method
is far easier and at least predictable stuff. I imagine someone initiating
objects at property declaration and then somewhere in the code assigning
the data they want the object to work with instead of just passing it in to
the constructor or calling a dedicated method to do that right after
creating an object.
