I've implemented a small companion class to boost.array that functions like a stack allocated vector with fixed capacity. The motivation for this class came when I was using boost.array in an interprocess library, when I realized that I actually desired an adjustable size boost.array, without the complexity of the vector class in the interprocess library. The result is StaticVector, which is boost.array directly modified with a size in front of the array, and added facilities to match std::vector.
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.
