from the preamble of the attached change set:

"Change Set:  IntervalIndexEnh
Date:   15 June 2004
Author:   Boris Gaertner

Interval inherits #indexOf:startingAt:ifAbsent: from SequenceableCollection.
The inherited method enumerates all elements until it finds a hit. Try

 (1 to: 100000 by: 0.01) indexOf: 99999

to see that this can be extremely time consuming. For Intervals, we can do

This enhancement assumes that the elements of an Interval are Numbers.
It is tempting to use intervals that contain instances of DataAndTime, but
this would require the generalization of some methods. "
