Pass variable-length arguments to another function expecting the same?

问题

How to code this right in Scala?

def myFun(strings: String*) = {
  // do something...
}

def myWraper(strings: String*) = {
  // do something else and then call myFun with the dame input
  myFun(strings)
}

I've tried putting an asterisk like

def myWraper(strings: String*) = {
  // do something else and then call myFun with the dame input
  myFun(strings*)
}

But this doesn't seem to work...

Try this:

 myFun(strings: _*)

You need to tell it to split strings up across the varargs.
