Currently, there's no way to allocate a dynamically-sized array on the stack. i.e. let x = [0; y] where y is an arbitrary usize. There are issues with stack exhaustion here, but rust already checks for it, and LLVM already supports dynamic arrays through C99, so, it'd be a very useful feature to have for systems which do not have a heap.
