Optional patcher

[piotrkosecki]

Hi. Can you provide something like optional patcher? The idea would be to do something like this:

case class Foo(a: String, b: Int, c: Double)
case class Bar(a: Option[String], b: Option[Int])

val f = Foo("aaa", 123, 0.33)
val b = Bar(None, Some(987))
f.patchWithOpt(b) should be Foo("aaa", 987, 0.33) 

At the moment the way I can do it is:

f.copy(a = b.getOrElse(f.a), ...)
