With VLAs, the buffer is on the stack whatever the capacity. With auto_buffer, the buffer is on the stack only if the capacity is smaller than N (which you define to be 256 by default).
I am wondering if there should be a default at all for N here as it seems like it is not really possible to make a good decision as to what that default value should be at the library level. If anything, I'd suggest at least having the default value able to be easily changed by users of the library with a #define. That raw, magic 256 at such a level is just a little scary to me. -- -Matt Calabrese
