Can I write an PHP extension to define "undefined" magic methods Follow

I have a class that handles dependency injection via __callStatic

$foo = Injector::Foo();  // <= returns a Foo object, either by passing a previously registered class for injection or by calling new Foo()

I've written a custom plugin that contains a TypeProvider3 which means that $foo is correctly typed as a 'Foo', but what I can't figure out is how to get rid of the Method 'Foo' not found in Injector.

I don't want a huge set of @method declarations, as that makes indexing take a long time, ideally I'd be able to add a separate extension in my plugin which could tell that inspection that this is a legitimate method reference.

Any pointers to what (if any) extension I could add to plugin to achieve this would be greatly appreciated.

Thanks,

Tim
