how do you make a property reference with that?

[sitepodmatt]

okay this is starting to sound familiar (although Im not sure I understood the answer in the early days)... can you elaborate

[jw]

is foo.bar a bound reference to the property Foo.bar on instance foo or an invocation of the getter of the bar property on the foo instance? The syntax is ambiguous.

[gildor]

class Foo {
    val bar: String = ""
    fun bar() = ""
}

Foo().bar // ???

[gildor]

Of course in theory it was possible to restrict such naming, but it would bring a lot of problems with JVM interop

next, why isn't this caught at compile time?

[gildor]

caught at compile time?

[sitepodmatt]

ah nevermind

[sitepodmatt]

::fn will fallback to use the property if there is no fun fn

[gildor]

Yes, reference to properties are also supported

[gildor]

but resolution may be ambiguous

[sitepodmatt]

thanks, til ☝️ everything above 🙂

For example you can do even this (but only if you don’t have ambiguous naming, like in my first sample):
