I think I understand how to deal with this, though I don't have all the code
working yet. The point is that the V of (K, V) can itself be a tuple. So
the updateFunc prototype looks something like
val updateDhcpState = (newValues: Seq[Tuple1[(Int, Time, Time)]], state:
Option[Tuple1[(Int, Time, Time)]]) =>
Option[Tuple1[(Int, Time, Time)]]
{ ... }
And I'm wondering whether those Tuple1()s are superfluous. Film at 11.
