sometimes need use several nested monadtrans . example, put maybet inside of exceptt , mimick continue , break in imperative programming: runexceptt . form [1..] $ \ _ -> runmaybet $ ... mzero -- mimics continue lift $ throwe "..." -- mimics break lift . lift $ putstrln "hello!" ... however, above code shows, every time need io inside of "artificial loop", need put ugly lift . lift before it. imagine if have more complicated nestings, , lot of io operations, becomes anonyance. how make code cleaner , more concise? for particular case of io , can use liftio :: monadio m => io -> m a lift io action through arbitrarily deep monad transformer stack: liftio $ putstrln "hello" this expression has type monadio m => m () . transformer stack contains instance of monadio somewhere inside of should have monadio instance itself, why works stack of depth.

i want know how access method sub-class of class when i'm in sub-class of same class... example: class foo { } class bar extends foo { public function something() { //do here } } class soap extends foo { $this->something(); //this method wanna call... } as can see wanna access subclass's method sub class. how do in php? you can directly, if soap subclass of bar : class soap extends bar { public function somefunction() { $this->something(); // work } } if it's not , still have option: obtain instance of bar , call method on it: class soap extends foo { public function somefunction(bar $bar) { $bar->something(); // work } } barring that, there's not else can do. since bar not in soap 's inheritance chain, there no way reference something using $this within of soap 's methods.

i have sqlite database read dataframe in julia. when values missing, given type sqlite.null, difficult deal with. prefer nas. there easy way conversion? kludgy way follows: using dataframes, sqlite df = dataframe() df[:x1] = [1, sqlite.nulltype(), 3, 4] df[:x2] = ["a", "b", sqlite.nulltype(), "d"] function repnull(x) if isa(x, sqlite.nulltype) return(na) else return(x) end end df[:1] = map(repnull, df[:x1]) df[:2] = map(repnull, df[:x2]) is there more elegant and/or efficient way? i've looked question i'm new julia may have been using wrong terms. the following seems readable , fast. for col in df.columns col[col.==sqlite.null]=na end a curious thing note 'exceptional' behaviour of na under equality. thus, above solution may throw exception if there na s in dataframe (i.e. operation not idempotent).
