Hi!

I'm wondering if it would be a good idea to have a `strict` mode in PHP.
Many language have them and it is a good idea.

I think it should be a bit different in PHP, it should encourage the
following things:

 - Avoid deprecated things, it should throw an exception.
 - Avoid explicit conversions of undefined constants to strings.
 - Anything else that could make run-time slower *or* bad practice.

```php
"use strict";

var_dump(FOOBAR); // should throw an exception, undefined constant.
```

Good idea?

Cheers,
