A modern programming language that makes developers happier.

hi guys ! 

interface SAMListener {
      public void listen(param1: Object, param2: Object)
}

myclass.setSAMListener {
   param1, (param2 as Boolean) -&gt;
}

I’m trying to make param2 autocast to Boolean, but it’s not working... Is there any way to do it in the prototype of the lambda ?

nitrog42: Does this really have to be in the method signature? Why not cast it in the body?

well i like the easy way :slightly_smiling_face:

I mean cast is ok  but require one more line, and param2 will always be a Boolean

It doesn't require one more line.
```
myclass.setSAMListener {
  param1, param2 -&gt; param2 as Boolean; !param2
}
```

yes but it’s not as fluent, I need to reuse param2, instead of driectly saying “i have param1 and param2 which is a boolean”

it’s not possible, but I hope in the future we can do things like that

Well... I hope not. :slightly_smiling_face:

There is no point in intruducing complexity to language for such rare usecases.
