(##sys#size X) will return the number slots/words in a vector-like
object, or the number of bytes for a byte-vector like object (i.e. a string)
(It will crash for immediate data). The result will not include nested data
structures.

"object-size" (lolevel unit) will return the number of bytes for all types
of objects, including nested objects. It will detect sharing.
