[Zope] aborting DTML parsing

[Sam Gendler]

I hope I don't get flamed off this list, but here goes...  I have recently had
to delve into ColdFusion for a customer, and there are some tags that would
certiainly be useful.  <CFABORT> for example, stops execution of a template.
They have some nice constructs in the <CFLOOP> tag as well, allowing loops
equivalent to while, for, and <dtml-in> loops.  There is a
<CFSWITCH><CFCASE></CFCASE></CFSWITCH> construct that I would certainly find
useful, too.  Don't worry, I have no intention of abandonning zope in favour of
CF, which is far superiour in SO many ways, but there is no reason not to use
their good ideas...

Didn't I see some reference to a <dtml-return> tag in version 2.1.  I haven't
checked the docs for new tags, but I thought I saw some email that mentioned
such a tag.  I might mention that there was no mention whatsoever of new dtml
tags in the CHANGES.TXT file.
