scala - safe Iterator.max -

Is there a library that provides functions like Iterator.max , but it Option [A] possibly due to a A account for blank eaterators? Alternatively, is there any library that provides class PosInf [A] or A to do this?

What to do for me, but using a library is always better to duplicate the code.)

: MA.maximum Usage:

  import scalaz._; Import Scalaz._ List (1, 2, 3) .maximum == Some (3) List.empty [Int] .maximum == Any   
 The only problem is that it is not You can work directly with Iterators, so you instead (like  Iterator.toStream )  
  list (using 1, 2)  stream < / Code>, 3) .iterator.toStream.maximum = some (3)
