whoops, category link

New page

There is no nice way to iterate over two collections in parallel, or correspondingly to write a generic "zip", since the existing protocol [[:Category:Message iterate/1|iterate/1]] is internal iteration.

==Proposals==

* Give all collections an operation to create EIO [[InStream]]s from them. This is basically external iteration. --[[User:Kevin Reid|Kevin Reid]] 14:58, 24 February 2009 (CST)

* Give all collections an operation to create functional streams (lazy lists) from them. --[[User:Kevin Reid|Kevin Reid]] 14:58, 24 February 2009 (CST)

==Discussion==

[[User:Kevin Reid]] and [[User:Markm]] have discussed this but not in text. XXX Kevin should write up the EIO/Dividoid plan and how the functional-stream option ties into this.
