Thanks for the example. Not unconceivable, indeed. That's a pitty.

And the above example even excludes any other possible delimiter...

It would be nice to extend tal:repeat's capabilities but it looks wrong to
me to do it with repeat-define and repeat-condition because they are at
syntatically "brothers-level" to all the other TAL tags when in fact they
are semantically at "children-level" of tal:repeat.

IMHO, either a tal:pre-repeat (Casey Duncan's proposal) or a tal:repeat-ext
(tal:repeat extended) would do a better job.
