When the decorator (method decorators) function is executed, we get access to `target`, `methodName` and `descriptor`.

I want to know the module path for `target` in this case. So basically the file path that leads to the module that called the decorator. How do I get this information?

I tried using the `module` object, ie `module.parent.filename`, but that one isn't safe to use as it doesn't update when the same decorator is used in another file - so it stores the information of the file where the decorator was first called.
