i have seen many clojure programmers enthusiastic new core.async library and, though seems interesting, having hard time seeing how conforms clojure principles, have these questions: it uses mutable state everywhere, function names suggest having exclamation mark, alt!, put!, >!, , others. if put or take value channel, channel modified inplace. isn't contrary clojure philosophy of preferring immutable data-structures, pure functions , on? or core.async made used mutable things not avoided @ all? since "go" macro (thus modifying code structure) , ensures "<!" used directly in go-block, not possible use "<!" inside function, this: (defn take-and-print [c] (println (<! c))) (def ch (chan 1)) (>!! ch 123) (go (take-and-print ch)) assert failed: <! used not in (go ...) block it seems me prevents simplicity , composability. why not problem? maybe consequence of previous 2 issues, lot of code core.async uses lower-level cons

write program checks how long name is. program should take name input user. if name has 3 or fewer letters, program should work this: enter name: lin hi lin, have short name. if name has between 4 , 8 letters (inclusive), program should work this: enter name: jimmy hi jimmy, nice meet you. otherwise, if name has more 8 letters, program should work this: enter name: yaasmeena hi yaasmeena, have long name. here's attempt returns "hi xxxxxxx, have short name" regardless of length. name = input('enter name: ') if name.count('name') >= int(3): print ('hi', 'name', ',', 'nice meet you.') elif name.count('name') <= int(3): print ('hi', 'name', ',', 'you have short name.') elif name.count('name') > int(8): print ('hi', 'name', ',', 'you have long name.') you should use len(name) , don't need int(3) 3

i have been racking brain on , off few weeks now... currenlty have this: a bunch of *service classes all of these depend on different *repository classes access database via ef to allow unit testing derivate of dbcontext injected repositories. (so can not use using dispose of contexts) to correctly dispose of ef contexts injected run dependency tree in inrequestscope() or in simple custom scope - inscope(c => new object()) on top level , in inparentscope() on other levels. both of these approaches create , dispose lot of objects during each request. in addition talking single page application 95% of queries (50 or so) executed during 2 requests inrequestscope() seems not idea. *service classes hold no state , insingletonscope() , minimize amount of object creation. the question is possible have parent *service , *repository classes in insingletonscope() , somehow inject ef dbcontext in scope return new instance each time accessed , honor idisposable
