This D2 code seems correct:


void main() {
    int[int[]] aa = [[1]: 2];
}


But DMD v2.046 prints at compile-time:

test.d(2): comma expected separating array initializers, not :
test.d(2): semicolon expected, not '3'
test.d(2): found ']' when expecting ';' following 'statement'

mind a bit more lookahead?

your code looks fine. dmd's parser doesn't honor the second line in

ArrayMemberInitialization:
    NonVoidInitializer
    AssignExpression : NonVoidInitializer

for array literals.

It compiles now, although I'm not sure if such a key should be allowed..

The type of the key of this associative array is actually "const int[]", despite the type signature says something different... So the keys are OK. It's the associative array type signature that is not good.
