Is there something in core or contrib that supports creating a map where gets on undefined keys return a specified default value? For example, I'd like to create a hashmap where the default value for missing keys is zero.
You can specify the default value when retrieving the value: (def m {:a 1 :b 2}) (get m :c 0) => 0 (m :c 0) => 0 (untested) maybe also: (:c m 0) => 0 (also untested) Sincerely Meikel
