It's a little easier to test modules while they aren't declared as such, the ones that aren't proper modules yet are ones that require more testing or general effort before I feel they're fit for it.
Yep, enumerations are EachIn friendly. I also introduced a function I think is immensely handy, and that is Enumerator.get(x). It allows you to enumerate over anything that is enumerable, so long as some function for returning an enumerator for it has been registered. Enumerator implementations can also have methods like hasprev() and previtem(), and others for modifying the target during enumeration such as add() and remove().
for local item:object = eachin Enumerator.get( who_knows_what_this_is_but_hey_maybe_it_can_be_enumerated_lets_find_out )
dostuff( item )
next
