Stephen Colebourne commented on LANG-588:
-----------------------------------------
I have no specific requirement for a List. However I would advise against an
Iterable, simply because its not that widely accepted in other APIs.
The ability to merge pairs into a single list will be a requested feature I
suspect.
As I said, I'm strongly against caching the hash code - premature optimisation
and unsafe with mutable classes.

> [lang] is the perfect place to provide a basic typed Pair class. I have
> written such a class for my employer (who hasn't?) but can/will rewrite blind
> to avoid IP issues. I think it's also nice to go ahead and extend this to
> MatchedPair<T> extends Pair<T, T> as well.
