I thought it would be helpful to have a complete implementation of how an Iterator would work, in this case the proposed implementation for the map operator in mildew (yes, the amount of indirection in SMOP kinda requires us to write it in a high-level-language): That code doesn't use any of the implied lazyness/eagerness of any operator, it uses the API directly, much of the effort in that code is going to be simplified to the user by the use of the feed operator... The code is in the pugs repo: http://svn.pugscode.org/pugs/v6/mildew/Map.pm daniel
