Sure, but a conversion operator implemented by the hypothetical
boost::string should suffice no? For interfaces that take an
std::string, that'd be all you need really. For those that need a
c_str(), then I guess it's the price you pay for a crazy efficient
string that you can use in the innards of your application and just
pay for the cost of when you just need a c_str(). :D

Of course I'm half-joking there, but I think that's a reasonable price
to pay I think much like how everyone is just dealing with the fact
that you absolutely have to at some point just linearize your data
structures into a void* for it to be sent through network APIs that
take a void* and a size. Maybe people want to have zero-copy APIs but
even Linux doesn't provide that API just yet at least to the
user-space applications so I don't see why having just an extra string
copy to an std::string would be a big deal.
