* InstallValue cannot handle immediate values, characters or
booleans for technical reasons. A check for such values was
introduced to trigger an error message and prevent incorrect
results caused by this.
* KnowsDictionary and LookupDictionary methods for
IsListLookupDictionary were using PositionFirstComponent; the
latter is only valid on sorted lists, but in
IsListLookupDictionary the underlying list is NOT sorted in
general, leading to bogus results.
