yes. it is quite easy to remember if you'll just read the declaration 
from left to right:
  int[3][2] arr
becomes:
  (int[3])[2]
i.e. "array of two (int[3]) items". no complicated decoding rules.

and then accessing it is logical too: first we'll index array of two 
items, then `(int[3])` array.

declaration may look "reversed", but after some time i found it 
straightforward to read. ;-)
