2020-08-03Use closures instead of ennum-exp objects.Arun Isaac
The lexical environment of a closure can capture all inputs to an expression. Earlier we were capturing some of these inputs using the inputs slot of an ennum-exp object. Capturing dynamically scoped global variables is a different matter, and is not addressed by this commit. * ennum.el (ennum-exp): Delete type. (ennum--rewrite-inputs): Delete macro. (ennum-eval): Deal with closures not ennum-exp objects. (ennum-store-item-union, ennum-publish-post, ennum-publish-generic, ennum-publish-feed, ennum-publish-image, ennum-publish-copy): Pass inputs as lexically bound variables of a closure, rather than as ennum-exp inputs.
