Re: functions inside of go blocks
You can definitely call functions, just not ones use the channel ops. The recommendation is to keep the io ops inside the go block and pull your logic into external functions. There are two benefits to this approach: 1) You keep all the impure io stuff together in the go block while putting your logic into pure functions. 2) Code in the go block has a performance penalty as it is being rewritten by the go macro - putting your logic into external functions avoids this penalty. If you really want to abstract code with channel ops, then you should use a macro. On Saturday, January 11, 2014 1:45:08 PM UTC-6, t x wrote: Hi, Consider this function: (defn try-put!

Re: functions inside of go blocks
I'm not really familiar with async, but why would you not be allowed to call that function inside a go block?

Hi Bart, !, !, alts! must happen within a _lexical scope_ of a (async/go block) On Thu, Jan 16, 2014 at 1:32 PM, Bart Spiers bart.ape...@gmail.com wrote: I'm not really familiar with async, but why would you not be allowed to call that function inside a go block?
