What If (for PHP)?

1. Single-directory packages
2. File-scoped visibility for classes/interfaces/enums/functions and variables?
3. Anonymous namespaces
4. include*() and require() support:
   • support for a stream context parameter
   • accepts an array of \PhpTokens
5. Convert an int into a resource
6. Limit parameter for:
   • get_declared_classes()
   • get_declared_interfaces()
   • get_declared_traits()
7. Allow stream_filter_append() to filter include*() and require()
8. Classes could extend based on an instance of another class
   • Allow hidden code to export the ability to subclass
   • without having to worry about same-named class conflicts

   $base = new Base();
   class Foo extends $base {}

9. OR classes could extend based on an instance of a Prototype object, and classes could implement based on a prototype

   $myClass = new \PHP\Prototype('MyClass')
   $myIFace = new \PHP\Prototype('MyInterface')
   class Foo extends $myClass implements $myIFace {}
