In some applications, the lion's share of business logic is concentrated in dynamic expressions. Often they are not even part of the code base and are stored in a database, files, or somewhere in the cloud. And sometimes these expressions need to be accessed non-technical personnel, like managers or call centers operators. Making them learn clojure or python is not fair. This library is designed to combine the best of two completely different worlds: the most understandable syntax from Excel and the speed of Clojure. Distributed under the Eclipse Public License, the same as Clojure.
