Hello Antony,

You did a nice work for the RFC.

However, I have to disagree with the name __assign, because it limits the
type casting operation only to assignments. An implicit  type casting could
very well happen upon calling a function with type hints.

Therefore, I would suggest the use of something like __castFrom(mixed
$value). Of course, this changes the semantics a little bit:
1. The function has to be static.
2. The function has to return the new object.

I would suggest to check out C# implicit casting, which does exactly this
thing (in compile-time however). Check this example:
http://msdn.microsoft.com/en-us/library/z5z9kes2.aspx

This way we don't mess up with the assignment operator. Meanwhile, there is
another interesting RFC under discussion (check the thread "Scalar Type
Hinting") which seems to be far more promising than overloading the
assignment operator.
