Couple of possible gotchas.  First, make sure you're using
sufficiently recent Nickle bits: we fixed some bugs a month
or so back.  Second, note that as they are currently
implemented, growable arrays aren't allocated until they're
initialized.  This is a bug, and should be fixed.  Finally,
note that until you've initialized a cell in the array, you
can't initialize its contents.

Here's some Nickle that works
  $ nickle

  (s [...]) {{x = 3}, <uninit>}
  > setdim(a,0)
