It always annoys me having to specify element count for things that aren't 
arrays.

I suggestion a single object allocation function, and an array allocation 
function that allows zero length arrays. Possibly also a must-not-be-zero 
array form if we think it's important.

Note that conversion to object/type based allocation is not always 
straightforward because inheritance means we don't have the final object type 
when doing the allocation.
