Subject: [boost] [array] - array_vector

I've a got a small utility class that is a cross between boost::array and std::vector for when I only have a compile time constant max things. This is beats to complexity of fighting with custom allocators/pools.
const unsigned n=100;
It's stl compliant and should drop in anywhere you've got a vector. Like vector and unlike boost::array (or regular array) 100 Things are not constructed.
Have I reinvented something in boost? Should I submit it?
Also related to this. There are a class of problems where n is known only on runtime, but you still only need it in a certain scope. gcc (C99 standard) allows variable length arrays on the stack. Does anyone know if that is allowed in C++11?
What would think about something like this?
placeholder<Thing> bufffer[n]; //variable length data on stack
