Re: List vs. array in Mathematica

The function Array does _not_ necessarily a list of uniform depth. For example:
f[n_] := Nest[List, x, n] Array[f, 5] (* {{x}, {{x}}, {{{x}}}, {{{{x}}}}, {{{{{x}}}}}} *)
However, the function ArrayQ does not return True for a "ragged" array but only she "all parts at a particular level must be lists of the same length.
