There are reasons to not mix ROUTER and PULL, mainly that they are from different patterns, so if we decide to improve PUSH/PULL as a package, we would be unable, if people were mixing them with other patterns.
As an example, see how we improved PUB/SUB to do pub-side filtering. DEALER does just the same as PUSH + PULL, so ROUTER/DEALER gives you what you want, and is better too, since you can do things like send heartbeats in both directions. -Pieter On Wed, Nov 14, 2012 at 4:02 AM, Justin Karneges <[email protected]> wrote: > Why not make it allowed in a future version?
