Exploring a number of concepts at the base of a programming language I discovered that it was possible to do without "closures", whatever their indisputable interest.<p>* <a href="http://lambdaway.free.fr/lambdawalks/" rel="nofollow">http://lambdaway.free.fr/lambdawalks/</a><p>* <a href="http://lambdaway.free.fr/lambdawalks/?view=unclosure" rel="nofollow">http://lambdaway.free.fr/lambdawalks/?view=unclosure</a><p>I wonder if such a language in which the management of the lexical context would have become useless could lead to optimizations. For example in recursive operations. What do you think about it?
