AA's are unordered containers. Do not rely on entries to appear in any
specific order when you traverse an AA; it is implementation-dependent
and may differ from OS to OS / platform to platform / sequence of
operations performed on the AA since its initialization / phase of the
moon. Any specific order that may appear in an AA is pure coincidence
and may not appear again next time, or may only appear again at 11:59:59
Feb 29 under a blue moon.
If you need entries in your AA in a specific order, extract them (or
their keys) into an array then sort them yourself. E.g.:
string[string] myAA;
auto keys = myAA.keys;
sort(keys);
foreach (k; keys) {
... // now keys will be in the expected order
}
