Just curious: what do you think of Andrei's work on policy-based strings: http://www.cuj.com/documents/s=7994/cujcexp1906alexandr/alexandr.htm http://moderncppdesign.com/code/flex_string.zip - does it do what you want (or leave flexibility to do what you want) - if so why not just use it - if not what doesn't it do m

Is there any interest in the ability to generate a basic_string compliant interface from a base set of functions in a similar way that the iterator adaptors work?

I am currently developing a fixed-capacity string class that complies to the basic_string interface and have at least 3 variants:

boost::fixed_string< n, CharT = char, StringPolicy = std::char_traits< char > > boost::char_string boost::wchar_string

where fixed_string derives from boost::char_string or boost::wchar_string depending on CharT. It may be useful to implement these like this:

struct char_string: boost::basic_string_impl< char_string > { // ... };

void myfn( char_string & s ) { // manipulate s like a basic_string or apply C-string functions }

So the question is this: are other people interested in this concept, or is it better placed as an implementation detail?

Regards, Reece
