Hey, maybe somebody can help me:
I try to create a property with a list of elements, where the element have to inherit from a specific class and has to implement a specific interface. I ended up in sth like this:
private val <T> buffer: List<T> where T : A, T : SomeInterface
Problem: this is not working since T is not used in "its receiver type" - can somebody help me with the correct syntax for my purpose?

you can’t really have call-site variance for vals

[Shawn]

I’m not sure what you’re trying to do is possible in the first place

[Shawn]

you may want a function instead, but I can’t say for sure

[karelpeeters]

I think he wants an intersection type, not actual generics.

[Shawn]

shame we can’t have List<T | SomeInterface> 😕

[rootandy]

no function is no option

[Shawn]

@karelpeeters true

[rootandy]

yes private val buffer: List<A & SomeInterface> would be another great option to show what I mean
