Hello,
Consider the following code snippet
def f1(i:Int) = {println(s"$i")}
def f2(i:Int, j:Int) = {println(s"$i $j")}
//Following compiles
val a = f1(_)
//Following does not compile
val b = f2(_, 2)
//Following compiles
val b: Int=>Unit = f2(_, 2)
The question is, why can Scala infer the type of f1(_)
correctly, while for f2(_ , 2)
, it cannot?
