Review comment:
I don't know, but I guess the answer is no. AFAIK, using order
preserving maps is a more recent thing (e. g. Google Chrome preserves insertion
order of JavaScript Objects, which are HashMaps as well. That's also not
required by the ECMA standards, but it's a neat feature, especially with
debugging etc.)
> Maybe we could apply the same behavior.
Why not? But that's always a feature, users can't rely on. In fact, it's
just _nice to have_, However, since `LinkedHashMap`is not much more costly than
a classic `HashMap` (especially with only few entries), there is no pain with
using it.
