Scala: pass Seq to var-args functions -


given function takes variable number of arguments, e.g.

def foo(os: string*) =   println(os.tolist)

how can pass sequence of arguments function? write:

val args = seq("hi", "there") foo(args)

obviously, not work.

foo(args:_*) trick. instead of applying sequence 1 single argument, each element in sequence used argument.
