as one former pillar of this community used to say: "this isn't Perl"
;-) hah. bet you never thought that would be used in favor of adding
a feature!
as for what would trigger the #else, i should think that is obvious.
the #else statement is rendered anytime the #foreach doesn't render
its innards for whatever reason. i think we can all very easily agree
on that!

i don't see how doing
#foreach( $result in $list_of_results )
$result
#else
No results to show!
#end
is any more business logic than your example.
and even if it is, i've always tended to side with elegance over
pure-MVC-ism (thus my interest in Pull-MVC and VelocityTools). ;-)
still the real deciding factor will be whether anyone steps up to
scratch this itch with a patch. i wish i could say i would, but i
know i won't ever get to it.
