A modern programming language that makes developers happier.

kotlinlang

Is there way to have method reference for optional receiver?
```                    customKeyListener?.onCustomKeyPressed()```
something like
```                    customKeyListener::onCustomKeyPressed```


```customKeyListener?.let { it::onCustomKeyPressed }```

yeah, it would be nice if we could do: `customKeyListener?::onCustomKeyPressed`

if `?` were to be usable standalone then `? ::` would work

I don't think that proposal has a serious chance of making it into the language as is though
