when passing objects as parameters to constructors, are those objects kept as references in the class being constructed, or are they released once construction is complete? eg

class MyClass(instance: MyObject) {
    val prop = instance.myFun()   
}

would

instance

be released as soon as construction had completed?

Then it would be captured I think.

"released", they're just constructor parameters, not actual fields.

@karelpeeters sure, but an instance of

MyClass

would still need to be passed a reference to

instance

in order to compute

myFun()

, no?

Yes, but all that happens in the constructor.
