Hi, there!

Please try the attached change set:  stream-chains.cs
<http://forum.world.st/file/n4889389/stream-chains.cs>  

It adds the possibility to attach transformations to streams using
generators.

Example:

foo := (#(1 2 3 4 5 6) readStream
   select: [:ea | ea even])
   collect: [:ea | 2 * ea].
foo upToNil. "#(4 8 12)"

It is tested. :-)

Thanks Patrick for the idea.

Best,
Marcel
