I don't think there is such thing as "a lack of C++ libraries".  It's just a 
few _key_ libraries are missing.

Not exactly...  the cost would be runtime -- to allocate a copy of the 
string.  You wouldn't be able to pass anything other than "std::string" to 
"const std::string&" without copying it first, would you?
