scala.js - Overload private constructor with polymorphic arguments in Scala -

i'm curious best solution in scala:

class myclass private (x: any, y: int) {   def this(x: int, y: int) = this(x, y)   def this(x: string, y: int) = this(x, y) }  val x0 = new myclass(1, 1) val x1 = new myclass("1", 1) //val x2 = new myclass(1.0, 1) // correctly doesn't typecheck 

the error below doesn't make lot of sense me, because appears viable constructor defined before auxiliary constructor:

error:(3, 31) called constructor's definition must precede calling constructor's definition   def this(x: int, y: int) = this(x, y)                          ^ 

for more context, i'm trying deal javascript apis in scala.js functions take parameter can either string or js.object, think exemplifies issue.

ascribing type any explicitly help:

class myclass private (x: any, y: int) {   def this(x: int, y: int) = this(x: any, y)   def this(x: string, y: int) = this(x: any, y) } 

in case, constructors call recursively, nonsensical.
