This is the object reference, and the values are, row by row, *in* this 
object. tal:replace doesn't iterate over the rows, but replaces the tag 
by the value of the object, which is this reference. Andreas has already 
answered how to use tal:repeat, so I don't go more into it...

Seems so. OO programming knowledge would help, too.

Use ZPT in Page Templates, DTML in DTML-Documents, -Methods and Z SQL 
Methods. That's that.

See above - ZPT is for design and layout, not for logic. "Better" means 
"closer to the ideal of separating content and layout" here. DTML mixes 
both and therefore is more a "write only language" (read: bad to 
administrate). In ZPT you additionally need Python for logic (which you 
needed with DTML for everything more complicated anyways...).

You should now understand why, and in which cases. Or not...?
