Apply a transform function to each element of an array. The block takes an int and returns an int.

// Apply a transform function to each element of an array.
// The block takes an int and returns an int.
void apply_transform(const TArray<int32_t> & arr, int32_t * results,
                     const TBlock<int32_t, int32_t> & blk,
                     Context * context, LineInfoArg * at) {
    for (uint32_t i = 0; i < arr.size; ++i) {
        // das_invoke<RetType>::invoke(ctx, lineinfo, block, args...)
        results[i] = das_invoke<int32_t>::invoke(context, at, blk, arr[i]);
    }
}

// A simpler example: call a void block with two arguments.
