I think some sugar can be added to the language for this. In the meantime you can use this from my D libs:

/***************************************
Return a new empty associative array of the given KeyType,ValueType.

Example: AA!(int, string);
*/
template AA(KeyType, ValueType) {
    const ValueType[KeyType] AA = AA_impl!(KeyType, ValueType).res;
}

private template AA_impl(KeyType, ValueType) {
    ValueType[KeyType] result;
    const ValueType[KeyType] res = result;
}

to be used as something as:

aaa char[int][];
foreach(_; xrange(10))
    aaa ~= AA!(int, char);
