I like it well enough, although with the proposed changes at
http://www.zope.org/Members/4am/DTMLWiki/NamedDTMLInLoop
I would prefer it to be a method of the iterator rather than a tag, so that
you would write:

<dtml-in sequence>
  <dtml-if condition><dtml-call sequence-break></dtml-if>
  <dtml-var sequence-item>
</dtml-in>

...or in the case of nested loops:

<dtml-in seq1 var=loop1>
  <dtml-in seq2 var=loop2>
    <dtml-if condition><dtml-call loop1/sequence-break></dtml-if>
    <dtml-var loop1/sequence-item>, <dtml-var loop2/sequence-item>
  </dtml-in>
</dtml-in>

Cheers,
