unsignedOverload_kt.cpp

is there a nice way to have an overloaded function that accepts all (nullable) unsigned types, and to call that function with `0u`? At the moment Kotlin doesn’t know which unsigned type to use, and errors with `Overload resolution ambiguity`.

closest workaround I can think of is to use different parameter names for each function


```fun operation(uByte: UByte?): Unit = operation(uByte.toString())```
and while there’s still an error with `operation(0u)`, at least it can be specified with `operation(uLong = 0u)`

It appears to be an issue
(<https://youtrack.jetbrains.com/issue/KT-46360>) that has been present for some time.

`0u.javaClass.typeName` outputs `kotlin.UInt`, yet it still prints this error on `operation(0u)`. You can use parameter names like you did with `operation(uLong = 0u)`, but you can also call one of the "casting" methods, such as `operation(0u.toUInt())`, `operation(0u.toUShort())`, etc.

As for a generic method matching all unsingned types, I'm not sure how. Looking at the API, it doesn't seem like they extend any other types like `Number`, they only implement `Comparable&lt;T&gt;`.

thanks for finding that issue <@U04DESYRM0D>
