Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

Nasal Loops

no edit summary
Nasal has several ways to implement an iteration.
A polling loop is akin to somebody permanently running to a room to check if the lights are on - a listener is like somebody being INSIDE the room SLEEPING and only WAKING up once the lights are turned on(there is no active workload involved here, other than basically "watching" the switch).
The {{func link|setlistener()}} API is intended to catch rare events. Avoid complex loops if you don't have to.
