In the case of StativVector<char,N> where N<256, you should consider 
using uint8_t to store the size - and similar variations.  
Boost.Integer makes it possible to select a suitable type.

I am wondering whether C++11's user string literal stuff could be used 
to select a suitable max string size at compile time.  For example:

auto s1( "Hello"S );  // S suffix creates a static_string<5> in this case
auto s2( "World"S );
auto s3 = s1 + ' ' + s2;  // Result is static_string<11>

I could imagine very efficient short string expressions done like this.
