Re: Question about sets
The new ticket CLJ-1065 has a patch that I think implements the desired behavior on the dev wiki page. i.e. set/map literals with duplicates are invalid (status quo) All constructor functions for sets and maps allow duplicates, and for maps, always take the value associated with the last occurrence of the same key. All constructor functions explicitly say this in their doc strings.

Re: redefining multimethods at the repl

I'm trying to write exercises for multimethods. Book readers will be

Re: Literate Programming in org-babel (ob-clojure.el) is broken under nrepl.el
On Thu, Sep 6, 2012 at 6:42 PM, lambdatronic gwjoh...@uvm.edu wrote: For those people (like myself) who do a lot of Literate Programming in Emacs using Clojure and org-babel, migrating to nrepl and nrepl.el is somewhat non-trivial. This is because the existing Clojure support in org-babel (ob-clojure.el) relies on slime and swank-clojure when running org-babel-execute-src-block (which redirects to org-babel-execute:clojure in ob-clojure.el). So clearly this is actually an issue for both nrepl.el and ob-clojure.el, not simply one or the other. All the same, I've hacked together a simple workaround that fixes the problem and makes Literate Programming under nrepl possible once again.

Hi Murtaza,
moustache handlers must be functions. So to return a string as a

[] (constantly Nothing was found)

Michael Fogus mefo...@gmail.com writes: Data formats do not exist in a vacuum. They are parsed by languages.

The concern I have is for someone wanting to define a format atop EDN -- or, to put it differently, to define a schema for it. If we want to define a structure to be represented in EDN such as a list of a person's favorite colors, on what basis would the schema author choose between list and vector notation? Is there a higher-level abstract type that he specify and require that a conforming processor accept either a list or vector literal? Even if he could mandate that, say, the favorite color list is of type sequence -- listed in descending order of preference -- then an author creating the EDN to represent such a person again has to make a choice between a list and a vector, again without a clear basis for his decision.

If we want to define a structure to be represented in EDN such as a list of a person's favorite colors, on what basis would the schema author choose between list and vector notation? Is there a higher-level abstract type that he specify and require that a conforming processor accept either a list or vector literal? Even if he could mandate that, say, the favorite color list is of type sequence -- listed in descending order of preference -- then an author creating the EDN to represent such a person again has to make a choice between a list and a vector, again without a clear basis for his decision. As an appeal to prior art, Rivest's S-Expressions Internet-Draft¹ used only a single list structure, though it does define three different encodings for that structure.

But that is not the *contract* of the fetch-val function. the docstring explicitly says that the state is a map and that the function returns the value corresponding to this key. This does break for a string or integer key. There is no way around it, this is a bug. As to the second issue, if you're worried about efficiency, a more general solution might be appropriate: one capable of expressing inlining for m-result and m-bind. Right now, you can always get efficiency by writing out your state monadic values rather than using the abstractions. This function stands alone in the state-m library in showing such an efficiency issue. One can see that great care was taken to make algo.monad efficient. I for one am very pleased about its performances. I'm merely asking to bring this single function up to par with its state-m friends. You'll notice that my preferred solution uses the same coding style as the rest of the state-m functions. Thanks for the JIRA link, I'm really not in the loop with these things.
