trait LazyParameters extends AnyRef

This trait can be used to allow some function to be called with varargs, with values being evaluated lazily:

def method[T](values: LazyParameter[T]*) = {
  values.toStream // use the toStream method to consume the values lazily
}
// usage
method(exp1, exp2, exp3)

Note that the values are really evaluated once, unlike a by-name parameter.
