We don't have anything like std::array, which is simply a wrapper around a standard C array and thus has no concept of a variable number of container elements. If that's what you want, please use a standard C array. :-)
If you want a container with a variable number of elements, but taking up a compile-time amount of space with no heap allocation, we do have a TFixedAllocator:
Here, the memory for the elements is inside the Array object itself. If you try to place more than 256 objects in the container, it will assert.
