Thank's for Idea, but it's not clear for me what result string is  
needed for this condtruction:
d.put("(('"NS"QList<"NS"QPair<"NS"QString,"NS"QString>  
 >'*)").put(d.data).put(')')->queryItems()");

Please write resulting string.

I know about this, I tried to show Idea.

Thank for help me to understand the internals of helper macros. I  
think it's very powerfull instrument and Nokia need to make good  
documentation about it.
