If I am correctly understanding the interpretation of Type_Name'Size
the attribute should return the minimum number of bits objects of this
type might require...
I believe Object_Name'Size returns the actual storage used for an object.
There is little correlation between Object_Name'Size and Type_Name'Size.
If I am wrong anyone feel free to post a correction. I am clearly NOT an
Ada expert.
-- Pretty much right. The only thing missing is that if the size of a
-- type is set using a size clause, type'size, subtype'SIZE, and
-- object'SIZE are all equal to the value set by the size clause. In
-- other words, if you ask for a specific size, that is the size for
-- everything of that type. (Except a record component whose size is
-- set differently by a record representation clause.)
