Can anyone come up with an example of a case where the call to clojure.edn/read leaves an unread character in the PushbackReader? Looking briefly at the EdnReader source, I only see cases where the pushback buffer is used internally, in order to save a character that is later consumed during th

Nice presentation (although I didn't see anything about comments. ?.). As I mentioned before, there seem to be significantly less examples of capturing semantic knowledge in names. I think a significant reason is the higher level abstractions you get to play with in FP and Clojure. This leads to

If you want to use memoize, then the clojure.core.memoize provides a more tunable version, which supports clearing the cache if required. https://github.com/clojure/core.memoize/blob/master/docs/Using.md -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Another path: write ClojureScript that consumes directly Nodejs and some popular web framework (like Express). Then, you can write the controllers/actions/logic in ClojureScript. I'm not sure about the feasibility of this idea from clojurescript. Angel "Java" Lopez @ajlopez On Tue, Dec 9, 2014 at

Maybe when you reach the async nature of node.js, you could use node fibers https://github.com/laverdet/node-fibers to wrap up async calls as sync ones, as a "baby step" to implement your ideas. Meteor https://www.meteor.com/ use a lot of fibers internally. Angel "Java" Lopez @ajlopez On Tue,
