ah, no, it's not. this is array of arrays, i.e. 'int[][]'. only static
arrays are guaranteed to be placed as one block of data. this will:

  int[2][2] a = [ [1,2],[3,4] ];

we have a nice PR from Kenji that allows the following declarations:

  int[$][$] a = [ [1,2],[3,4] ];

but alas, it's not in the mainline yet.
