-You can also  query an array for  the first match by  using #(...), or
-find all matches  with #(...)#. Queries support the ==,  !=, <, <=, >,
->= comparison operators  and the simple pattern matching  % (like) and
-!% (not like) operators. Eg:
-
-friends.#(last=="Murphy").first    >> "Dale"
-friends.#(last=="Murphy")#.first   >> ["Dale","Jane"]
-friends.#(age>45)#.last            >> ["Craig","Murphy"]
-friends.#(first%"D*").last         >> "Murphy"
-friends.#(first!%"D*").last        >> "Craig"
-friends.#(nets.#(=="fb"))#.first   >> ["Dale","Roger"]
