Probably not.  An association list is just a list of cons
(and thus may also be a list of lists).  Whether to treat it
as a "simple" list or an association list just depends on
the function which the programmer calls on them, there is no
"association list type".  A vector on the other hand is a
different data type and can thus be discerned from (associa-
tion) lists.
