Copy Case Class While Changing Some Values

One of the built in features of case classes is to make a copy while changing some of its fields:

#copy(argument = new value, ...)

Example

case class Foo(bar: String, baz: String)

val foo = Foo(
  bar = "bar",
  baz = "baz"
)

val differentFoo = foo.copy(baz = "qux")
