Description
I was looking at https://github.com/ruby/rbs/blob/c64d1f5ba5a4fbc95ffb1d72d783ee39b17d60fe/stdlib/builtin/builtin.rbs, where a lot of common knownn interfaces are stored. I was wondering whether there should be one for "callable" objects, that is: implements #call. Objects implementing this interface can already be passed to places where are expected, for example.
interface _Callable
def call: (*untyped) -> void
alias [] call

Research direction
Start with stdlib/builtin/builtin.rbs and review the existing common interfaces around the proposed _Callable entry. Compare the proposed call and [] signatures with nearby conventions; done means the accepted callable interface is represented there and the builtin signatures remain valid.
