+1 as well. I could never understand why page templates used 'here', 
scripts and views used 'context' (or self.context for views) and 
expressions used 'object'. We have moved away from 'here' in page 
templates, and settled on 'context', so why keep the inconsistency in 
TALES expressions? I get it wrong nearly every time I write one. :)
