Some of the solutions that use macros (Clojure, Common Lisp, Scheme, other?) result in code where the second condition is expanded twice, and thus partially defy the purpose of the new language construct (see the task description: "the code generated by the compiler might be unnecessarily large"). Better solutions might involve direct function calls instead of macros, or variables to keep temporary results. --[[User:Abu|Abu]] 09:15, 31 December 2010 (UTC)
