Some of users of intarray contrib module wish to use its features with another kind of arrays, not only for int4 type. Suggested module generalizes intarray over other (not all) types op pgsql.

Anyarray also provides a calculation of similarity two one dimensinal arrays similar to smlar module. Anyarray module doesn't provide an something similar to query_int feature of intarray, because this feature is very hard to implement (it requires new pseudo-type anyquery), it is close to impossible to have operation extensibility and it's complicated queries are hidden from pgsql's optimizer (like to jsquery). As far I know, query_int isn't very popular for now.
