Fix compile

[tkawachi]

In scala-library 2.13.6, I confirmed that there are two argument lists, but in https://dotty.epfl.ch/api/scala/collection/immutable/TreeSet.html, it looks like there is only one argument list for the constructor.

I tried with scalaVersion := "3.0.1" then scala-libary 2.13.6 is used. I don't know where there's the updated stdlib.

To aid migration, Scala 3.0.x uses the 2.13.6 standard library as-is.

Perhaps it's a Scaladoc bug?

Apparently so. It seems that empty argument lists, regardless of whether they are constructors or functions, are accidentally disappearing from scaladoc.
The following code confirms this.

class C1()(implicit i: Int)
class C2()(using i: Int)

class C {
    def f1()(implicit i: Int) = i
    def f2()(using i: Int) = i

    def f3(s: String)(implicit i: Int) = i
    def f4(s: String)(using i: Int) = i

    def f5()()(using i: Int) = i
}

The HTML generated by scala 3.0.1 looks like:

Thanks for reporting! Yes, that seems to be an issue in Scaladoc, so I’m closing the issue here.

Sorry, I didn’t see that there was an issue in the documentation as well… Thanks for the fix!
