VBA: collection as dictionary value?

Hi All,

Is it possible to use collection as value of a dictionary in VBA? For example, I would save authors and their books in such a dictionary. In C++ we can use

map<string, set<string> > authorsAndBooks;

to realize it.

If it is possible in VBA, an simple example with creating, adding data, retrieving data and iterating through it would be very helpful to me. Thanks!
