I suppose this is a lie, because NIL is used only if you say
:initial-element nil. Otherwise, the array is "unfilled", which means
0 (of the appropriate type) for cmucl.
Rodrigo> in another we have (:INITIAL-ELEMENT T), meaning the default is t;
but
If this is from the declared argument types part, that's just saying
the type of the :initial-element argument has type T. That is, it can
be anything.
