Re: whats the meaning of alias ?

As I understand it, the Clojure reader expects to be able to resolve namespace references as soon as it sees them. Since alias is a function, the c alias doesn't exist until sometime after the reader has already run. I think you will encounter a similar problem with the import macro. Ok,

Re: whats the meaning of alias ?

Hi ! Now that you understand it, can you explain it me? :) - I said it makes sense not that I understand it ;-) The make sense part is: Calling alias inside a do is something I probably won't do in production code. It would make more sense to

Re: question regarding agents

Thanks for the answer. Wrapping a mutable thing like an output stream in an agent seems dubious to me. It was intended to use an agent here since I need to control the access to the write object. But what I forgot was ' the validator succeeds or if no validator was given, the return

You mention threading in the subject and you have a (binding [...] ...) form. Are you starting a thread, or communicating with one, or using pmap, future, an agent, or etc. inside the binding, and expecting the binding to affect the code that runs in the thread/ map/future/agent?
