I'm looking at the operator definition and found a bunch of places where the "lambda" functions do not have wildcard bounds specified, e.g.,
reduce(Func2[T, T, T])
max(Comparator[T])
etc.
Is there a particular reason these are not:
reduce(Func2[? super T, ? super T, ? extends T])
max(Comparator[? super T])
?
