X-debbugs-cc: jporterbugs@HIDDEN

I am trying to run a series of tests like this:

    % for test in tests/tests/tagupl* { tests/using-intree $test }

I want the command to give up as soon as one of the tests fails.  But I
don't think there is any way to break out of the loop?  In POSIX sh, you
could use 'break'.

Thanks.

I actually have a patch sitting in my pile of branches that does this, 
but it needs a fair bit more work to get right. The main thing it needs 
is to keep 'break' from bubbling up too far (e.g. if you run an Eshell 
script from inside a loop, 'break' at the top level of the script 
shouldn't break out of the parent loop).

Another way to do something like this would be to embrace the Lispy-ness 
of Eshell and add a command-form for 'throw' and 'catch'. Something like:

   catch my-tag {
     for i in *.el {
      do-stuff
      if something-or-other { throw my-tag }
     }
   }

Or even support both 'throw'/'catch' *and* 'break'...

Heh.  throw/catch seems like overkill to me but supporting both would be
cool!
