Hi guys, is there a better way to express a delegated property
`var mapType`
    `get() = map.mapType`
    `set(value) {`
        `map.mapType = value`
    `}`
I know we have Delegates but can those be used in a more simple way than my implementation above?

You’d have to implement the `setValue` and `getValue` operators for whatever type `map` is then you can use `var mapType by map`

The delegate pattern where you implement the operators is really only useful if the type is delegated to a lot. For one-offs using the backing field directly like you have is perfectly fine.

OK, thanks. Then I already have the shortes implementation . Thought there would be something like
`var mapType by proxy(map.mapType)`
or even
`var mapType proxies map.mapType`
somehow generic. Quiet common use case when encapsulating 3rd party components.

You can probably write something to do `var mapType by proxy(map::mapType)` if you’re using it a lot, and then write it up as a suggestion for stdlib
