Yes, this is a bit mind disturbing. If you consider each syntax independantly,
they are both completely logical:
* type def: since T[2] defines an array of 2 T's, then T[2][3] well defines an
array of 3 arrays of 2 T's.
* element access: as your literal [[11,12],[21,22],[31,32]] well shows, the
2-element arrays are the nested ones; so that, to access an element, one must
first access a 2-element array -->
arr[2-element-array-index][element-index]
which maps to
arr[row-index][element-index]
as one expects.
But the confrontation of both logics is somewhat troubling ;-) To solve it, one
would need to reverse the
array definition format: [n]T means array of n T's, [m][n]T means array of m
arrays of n T's.
Simply forget about it and use each syntax according to its own point if view.
