ensure should catch break... break strikes me as being identical to an
exception that's caught at the end of the loop.  Truthfully though, I
was more excited about catching the case when a loop wasn't entered
(ex: 0 rows from the DB), vs when a break is thrown.  If you want an
"else", then use a normal exception block... though it is nice sugar
to have in the language I suppose (albeit slightly confusing to the
uninformed).  <:~)  -sc
