### Gleam Actor Example: Basic Usage

Source: https://hexdocs.pm/gleam_otp/1.2.0/gleam_otp/index

Demonstrates the basic usage of Gleam's actor system. It shows how to start an actor, send messages, and receive replies. The actor maintains an integer state and handles 'Add' and 'Get' messages.

```gleam
import gleam/erlang/process.{type Subject}
import gleam/otp/actor

pub fn main() {
  // Start an actor
  let assert Ok(actor) = 
    actor.new(0)
    |> actor.on_message(handle_message)
    |> actor.start

  // Send some messages to the actor
  actor.send(actor.data, Add(5))
  actor.send(actor.data, Add(3))

  // Send a message and get a reply
  assert actor.call(actor.data, waiting: 10, sending: Get) == 8
}

pub fn handle_message(state: Int, message: Message) -> actor.Next(Int, Message) {
  case message {
    Add(i) -> {
      let state = state + i
      actor.continue(state)
    }
    Get(reply) -> {
      actor.send(reply, state)
      actor.continue(state)
    }
  }
}

pub type Message {
  Add(Int)
  Get(Subject(Int))
}
```
