I'm having a compiler error when I try to use property access syntax instead of regular method setter. This is with using the Java XGBoost library.

```
val dmat = DMatrix(features, features.size, 1, -1.0f)
dmat.label(labels) // generates compiler error
dmat.setLabel(labels) // works fine```
The complier error is:

Unresolved reference. None of the following candidates is applicable because of receiver type mismatch:
public operator fun &lt;T, R&gt; DeepRecursiveFunction&lt;TypeVariable(T), TypeVariable(R)&gt;.invoke(value: TypeVariable(T)): TypeVariable(R) defined in kotlin

Anyone knows what is causing this behavior?

Not sure  what I was thinking of, I guess got confused by error. But of course indeed that works. Thanks!!!
