[Feature request] generics in overload

As far as I know, it is not possible to use `@generic` in `@overload`?

I have a table `Object` that has a `__call` metamethod, so class Object can be used as function: `Object()` == `Object:new()`
... And I want to overload class Object with function `new()`. This function use generics 🤯

No files, tests, or entry points are named. Start by locating how @generic and @overload are parsed and represented, then determine the intended syntax and behavior for combining them; done means the supported Object() overload with generics is specified and covered by appropriate tests.
