Re: Use of io!
Yep,wrap code that has side effects, prevent it to be evaluated in STM transaction. 2013/5/30 Maik Schünemann maikschuenem...@gmail.com I think It stops other code to wrap around the code with the explicit io! call. Its declarative way of saying: I am doing io! DONT USE me inside a dosync.

Re: Use of io!
Thanks guys. Now i understand its for marking functions containing io so that they blow up if they are used inside transactions. I am still learning clojure and i have decided to take some time to understand every function in the core API. Josh.

What if you really want the 'bad' effects on retries?

Re: Use of io!
Well, more seriously, I would be against any facility that prevents me from doing something potentially useful that I might want to do. Sprinkling potential problem spots with io! might make more sense in an application than a library.
