One general solution could be to have a hidden argument (managed by clojure) which holds the context, in some sort of map. Though, the map could not just be persistent, if one still wants to allow dynamic scope to be set!, and it could be broken when passing a Callable explictly to jav framework ... still need to think about it more ;-) > > On Wed, Jul 1, 2009 at 9:29 AM, Laurent PETIT <laurent.pe...@gmail.com> > wrote: >> >> Hi, thanks for the pointer ! >> >> By the way, I was wondering whether error-kit can be leveraged >> seamlessly with concurrent programming ? >> >> For example I guess that using (vec (pmap ...) instead of (vec (map >> ...) will not work because the binding of the handlers will be lost. >> >> I have always been ashamed by this consideration, and frustrated that >> I can't think about a way to free the developer from having to keep >> this in a corner of his mind ...
