Thanks for your help. That worked fine! I have one more question or suggestion. In the sample is used the following construct: my_map(bimap_instance).find(key_type_inst); my_map(bimap_instance)[key_type_inst] = value_type_inst; As I can see I can apply not only find but any other function supported by the interface. my_map is a function which returns me an object that supports the find or operator[] functions. To be honest, I don't like the idea of typing these long constructs. Why is there no design for such a construct: my_map tagged_bimap(bimap_instance); Then I can use the tagged_bimap as: tagged_bimap.find(key_type_inst); tagged_bimap[key_type_inst] = value_type_inst; With Kind Regards, Ovanes Markarian With Kind Regards, Ovanes Markarian
