Subject: Re: for ... else ... end

For the keyword war: (silly, dummy example)

cnt=0
for i in anArray do
  break if i<0
  res=19*i+4-i
  puts res
  cnt+=res
else
  puts "Empty array"
on_exit
  puts "The result is #{cnt}"
on_break # or on_abort
  # ok, I admit it is like an exception...
  puts "Invalid negative element found in the array!"
end

So, in any kind of loop:

else : code block is not executed
on_exit : code block is  executed, and terminated normally
on_break / on_abort : code block executed and exited via 'break'

These modifiers are in connection with the whole loop, not one
iteration, so perhaps another arrangement will be better.
