I think it is a useful and concise syntax for a not uncommon requirement.

Consider the current incarnation of the JobBoard example. The method 
JobList.getApprovedIds returns a list of job ids.


<tr tal:repeat="jobid context/getApprovedIds">
     <td>
     <a href="jobid" tal:attributes="href jobid">
     <span tal:replace="context/?jobid/summary">A job summary</span></A>
     </td>
</tr>


The alternative is to use a python expression. I much prefer a simple 
syntax for interpolating paths.

     <span tal:replace="python:path('context/%s/summary' % jobid)">
       A job summary</span></A>
