Given an assosiative array : int[string] k, is there a way

I can come up with a primitive soluiton:
int[string] k;
// populate k here
int[string] j;
foreach(sttring key, int val; k)
{
j[key] = val;
break;
}
but could it be better? it is wroth noting that the keys are
not known beforehand.
If you want something like a hash table that preserves insertion
order, you could try using an array of tuples instead. Then to
"pop" the first element, just do 'arr = arr[1..$]'.
