This is probably the best characterization of the traits/policy distinction I've heard. I don't agree entirely about basic_string, however; I think that the comparison functions such as char_traits::compare have to be made available through template parameters, otherwise you wouldn't be able to reuse basic_string if you want strings with different comparison criteria.
I thought it was already common knowledge that the idea of using the 'char_traits' policy parameter of basic_string to override comparisons is inherently flawed. Usually the kind of comparison you want depends on the context where the string is used, not on the type of the string.
