Code War: Quick Structure Check

I will be working with multidimensional data that will be required to
adhere to strict structuring.  A simple example would be a 3D array.
sequence s
s = repeat(repeat(repeat(0,2),3),4)-- this is equal to.
s = {
     {{0,0},{0,0},{0,0}},
     {{0,0},{0,0},{0,0}},
     {{0,0},{0,0},{0,0}},
     {{0,0},{0,0},{0,0}}
    }

Testing specifically for this exact structure is very easy.  HOWEVER, there
is a slight twist to the assignment.

s = {                       --this should fail.
     {   0 ,{0,0},{0,0}}, --error
     0,                   --error
     {0, 0, 0, 0},        -error
     {{0,0},{0,0},{0,0}}
    }

s = {                       --this should pass.
     {{} ,{0,0,0}},
     {{0,0},{0,0},{0,0},{0,0,0}},
     {{},{}}
    }


Notice that if it is declared a sequence then it MUST be a sequence BUT it
doesn't have to be of the exact length requested.

Any clues on how to QUICKLY handle this versatility.  I will be writing a
slow recursive calling routine to handle this for now.  I would much prefer
some sort of magic using sequences and compares or something of that nature.
