Hello

First sorry if this was already discussed. Tried to search on the 
archives but didn't find any relevant result.

If this was already discussed, just say so and forget my email :)


Was reading Kolon syntax manual for Text::Xslate and found the else 
block for for blocks interesting:

   for my $val (@array) {
      # do something
   }
   else {
      # say we do not have any values to process
   }

Would this be useful?
Not sure about implementation details, though...

cheers,
ambs
