           Summary: Increment (++) operator on a BigInt array item
           Product: D

I think this used to work:


void main() {
    import std.bigint: BigInt;
    BigInt[] arr = [BigInt(1)];
    arr[0]++;
}


dmd 2.066alpha gives:

temp.d(4,11): Error: var has no effect in expression (__pitmp1470)
