Description:
------------
Its interesting that PHP has had operator overloading in PECL for such a long time, but never implemented with PHP core. 

Come to think about it, C# has operator overloading, Python has operator overloading, Ruby has operator overloading too. The only major programming language that can be used for server side programming without operator overloading is, Java! I thought PHP internals dont want PHP to behave/look like Java?

-> and paamayim nekudotayim are supported for years using __get and friends.
`isset` and `empty` for not much less.
[] is supported with `ArrayAccess`.

= operator is not re-implementable for reference-only languages, because it doesn't refer to an object.

Comparison and large part of arithmetic operators are currently¹ not implementable in languages that are not strongly typed².

What can be added is:
 - unary + (have you ever used this one?) and unary -
 - / and %, but use cases are quite limited, especially in case of a WWW-centered language.
 - << and >>, with even more limited use cases
 - || and &&, but it could only be a couriosity.

¹ In theory they're implementable, but calls are prohibitely expensive. Beybe in future this will change.
² Neither Python nor PECL/operator really work. They just give illusion of having operators, but the solution is inherently broken.

The operator PECL package have not had a release for 4 years and development activity seems to have ceased, if a new maintainer picks up this package, then this report should be re-opened
