Part of the problem with this whole notion is that we are only
_initializing_ the list to contain one element. Nothing prevents us
from adding other elements. So it is _not_ a singleton list, even
using your definition!

Hmm. Ada.Text_IO.Create (file: file_Type) _does_ initialize an
object of type File_Type, and List.Create (the_list : list)
initializes an object of type List, so they are similar in meaning.

I really wish that last function call was List.Create (List : in out
List_Type). But that's another issue :)
