Varargs, method reference and SAM conversion

[Collin Fagan]

Hi Remi,

Just to clarify, you would like varargs paramaters to be .. um, "flattened"
(unwound? de-vared?) when checking for compatible method signatures during
method reference assignment?

That sounds cool, would you think a method that has a vararg should also
compatible with methods that take none of the vararg type?

interface PrintOneString {
  void printOneString(String value);
}
PrintTwoStrings  pts = System.out#printf;
pts.printOneString("value");
