Implicit arguments

I’m not an expert wrt. the spec, but intuitively what would it mean? The asterisk usually stands for “supply 0..n arguments here”, whereas for implicits you need exactly one in scope (simplifying intentionally).

This might be a simple question but its puzzling me.I have a method:

def using(target: String)(implicit conditions: ValueCondition* )...

How can I define an implicit argument?

Defining something like below is already illegal: 

implicit val conditions:ValueCondition* = 

Thanks

Hi Oleg,

maybe there is no way to define a corresponding implicit value if you
stick with a repeated parameter.
But you could live with the following:

type ValueCondition = Int
implicit val myConditions = Seq.empty[ValueCondition]
def using(target: String)(implicit conditions: Seq[ValueCondition]) {}
using("A")

It would be interesting though if there would be a way to ask for all the implicits that are available..
