'From Squeak3.10beta of 22 July 2007 [latest update: #7145] on 4 November 2007 at 8:30:48 am'! "Reporter: Damien Cassou Summary: 0006583: PositionableStream>>back behavior is totally wrong Description: The current method #back is a misconception about what a stream is. A stream contains a pointer *between* elements with past and future elements. This method considers that the pointer is *on* an element. Attached changeset: - renames #back to #oldBack for backward compatibility - implements #back - adds 4 tests. Please consider unit tests in the changeset which verifies #back and #oldBack behavior.
