(tab key 34) => ; returns 34 instead of nil when key is not present
I found it when I came across the comment before ar-apply. I've sent kens a documentation patch.Once I knew to look for it I found a couple of previous mentions: http://arclanguage.org/item?id=9525, http://arclanguage.org/item?id=8566 (tangential - it shows the code) Incidentally, arcforum.searchyc.com is awesome, once I found it. It makes me wish we could collect top-level resources on a page somewhere. We need that wiki after all (http://arclanguage.org/item?id=11088) |
