Dear All,

I suggest an improvement over foreach on objects:

Now works: foreach (item; container) { ... }

Should be added: foreach (item; container_obj.apply1) { ... }
foreach (item; container_obj.apply2) { ... }

This way we could have iterators which iterate over only parts of the container:

-- hash.keys
-- hash.values
-- hash.pairs
-- file.lines
-- file.chars

I'd also like to suggest a syntax sugar: for and foreach could be synonyms, just as in Perl.

I understand the need for this, and I think I have a way to make it work. Stay tuned!

It makes it easier to parse them if they are separate.
