It sucks a bit that ?.let {} doesnt use the extension function when receiver is dynamic. Anyone found a pattern just as concise way to express it ?

[gildor]

what do you mean?

[diesieben07]

foo.let {} does not call kotlin.let if foo has type dynamic

[diesieben07]

Because with dynamic everything is dispatched as normal JS function calls.

[diesieben07]

(foo as Any?)?.let { } should work though

[spand]

Except I need it as dynamic in the lambda

[diesieben07]

Maybe just use an if then? 😄

[spand]

Yeah thats what I am not quite satisfied with hence the question 🙂

[diesieben07]

Yeah I don't think you can do anything except cast to Any? outside and then back to dynamic inside.

[gildor]

ah, I see

[gildor]

I remember some discussion about this, as I remember only cast to Any will help

[diesieben07]

Well, that will fail if the object is null or undefined

[gildor]

undefined of course

[gildor]

but why null cast to Any? doesnot work? (foo as? Any)?.let{}

[diesieben07]

It doesn't? That's strange.

[gildor]

I see
