include foreach.e
function do_something(integer x, object item, object extra)
   -- Do something with the item
   return 0
end function

sequence result
result = foreach(pairs, routine_id("do_something"))
if result[1] = 0 then
  -- No problems
else
  -- Something went wrong
end if

 

I know about 'foreach' as I use it all the time in the D programming language. D
is a bit like a static-typed, object-enabled, compiled Euphoria.

I also use it in the Progress 4GL (OpenEdge) which is a proprietary database
language.
