dictionary sort in sortedmap

I want to sort a map by its keys according to dictionary when i do the following (into (sorted-map) {"1" "A" "2" "B" "11" "C" "3" "D"}) the result is {"1" "A", "11" "C", "2" "B", "3" "D"} which is expected result but what i expect is dictionary sort, {"1" "A", "2" "B", 3 "D", "11" "C"}. is

Thanks for the feedback Andy. I had a console-only emacs installed but I've reinstalled and confirmed one with X works. I was expecting a console editor to work as well as it does in ruby e.g. system("emacs -nw") but I'm guessing there's a limitation for java. Calling X emacs works for my use case

Clojure - Python Style suggestion

Hi, For us as Clojure community it is easy to see how Clojure benefits from being a Lisp. Homoiconity, extreme conciseness, esoteric look and feel, etc. However it is hard to see from the inside how Clojure as ecosystem (probably) suffer from being a Lisp. Please don't throw rotten eggs at me, I

Parens actually don't complect, they have a very very clear meaning. They organize functions and arguments. Let's take one line from your example: filter smaller xs Sois that the python equivalent to which of these? filter(smaller(xs)) filter(smaller, xs) filter(smaller(), xs()) filter(small

Re: Clojure - Python Style suggestion

Sergey's example code seems to have arguments to a function happen on the same line while new function calls appear on new lines. So: filter smaller xs ...would be the equivalent of filter(smaller(xs)). Anyway, I agree that parens don't add any more clutter. Having to *always* have all the arg

Re: Clojure - Python Style suggestion

I can't see the community migrating to such a syntax, even if somebody bothered to implement a reader for it. For me, the parentheses are vital in editing my source code. With lisp, I'm editing faster than with any other language, thanks to paredit. Regarding people seeing parens as an obstacle: O

Re: Clojure - Python Style suggestion

Again, I don't think it will help attract new users, at least not the way we want. Parentheses are an important part of the language and it's not something a beginner can just pick up later.

Basically each lambda compiles into a method body, and the size of its lexical environment doesn't matter very much, only the amount of code inside the lambda's (fully macroexpanded) body. So in (fn a [x] (foo (letfn [(b [] (bar)) (c [] (baz))])), a only "pays for" foo, and b and c pay for bar
