What is the significance of 'implicit' in this code block? I have seen such code in a few places in my project. How should I be using it to leverage 'implicit'.

implicit val a: Int = 10
val decorate: Int => Int => String = x => implicit y => {
  "*" + x + y + "*"
}
println(decorate(5))

I expected it to print

*510*

but it only prints the partial function representation itself

how aboud `def decorate(x: Int)(implicit y: Int) = s"*$x$y*"` – counter2015 Feb 17 '22 at 07:14
this works, but why does not the above work? – beegee Feb 17 '22 at 08:57
