Any ideas how to implement variable length arrays under -betterC?
variable-length arrays (i.e. slices) are valid in betterC. What isn't
allowed is *GC-allocating* them and *appending* to them in betterC.
```d
int[] arr; // fine
// arr ~= 5; // nope, uses GC
arr = (cast(int *)m

Nope.
-betterC means you have no runtime or standard library support.
You are very

You need a struct with operator overloads and libc realloc(),
(very) basically
```d
struct Array(T)
{
private:
struct Payload
{
T* ptr;
size_t length;
}
Payload p
