I've used arrays in countless OO and non-OO programming languages, and I do not recall ever having to manually calculate the size of objects contained therein – what are you talking about? Only C requires crap like that, but precisely because it doesn't have first class arrays.

Downvoters, care to elaborate what you think is wrong with the above? Literally even fortran can do better than

   size_t len_a = sizeof(a)/sizeof(a[0]);

or

   my_pseudo_foo_array = (foo*) malloc(len * sizeof(foo));

You're not wrong. Even BASIC was better than this.
