Please try it now.

Thanks! In addition to your patch, I have applied the following patch

 template asOpenArray*[T](a: VarLengthArray[T]): openarray[T] =
-  cast[seq[type(a[0])]](a)
+  toOpenArray(addr a.data[0],0,a.len)

using the new? toOpenArray function from system.nim

I am pondering about adding a VarLengthArray which lives on the heap.
Probably one has to use create and dealloc

Thanks, I'll make that change as soon as I have some time. Also, it's come to my attention that the test suite is deficient. Oh, BTW, PRs are welcome!
