Sean, your suggestion yields the following:
At first I came up with the same solution as your second one. But I
couldn't help but feel that it wasn't descriptive enough. It felt too
incidental-complexity-ish.
To me, (into {} the-map) seems mostly right. But obviously it would just
squash the values you need. So I figured it should just be
Wow. Sorry for the awful formatting. Re-pasting it from Google Groups
(instead of email) to fix it:
(def a [[:a 1] [:b 2] [:a 3]])
(defn add-maybe [ nums]
(- nums
(remove nil?)
(reduce +)))
(reduce (fn [m [k v]]
(update-in m [k] add-maybe v))
{}
Oh. Wow, I should read the whole thread before posting. Seems like
merge-with is what I was looking for. Although, lately both partial and
apply make me a little uneasy in terms of efficiency. But that's easily
enough solved with an anonymous function, which I don't think is any less
readable
Of your proposed solutions, this one
(defn to-consolidated-map [parts]
(- parts (map (partial apply hash-map)) (apply merge-with +))
Is the one I thought of first and also find very readable.

Sean, it sounds like you want

But that's based on some pretty limited context.

I'm trying to create this Domain Specific Language:

What it should do is to search for all files in a specific directory using

Some Java frameworks will accept public final fields as Java bean fields.
In that case, a Clojure record can be used directly (although I'm not sure
if we're making an assumption about Clojure records that might change).
This has actually worked for my limited needs in this space.

After upgrade to 2.3.1, I can't find repl-port file in target directory,
so lein repl will use a random port, I have to use LEIN_REPL_PORT=33021

Thank you!
I've upgraded our team to 2.3.1, as well as our QA system.
Interesting discussion - I was pretty surprised to see this can happen
I don't understand all the details about the solutions discussed in this
thread, but it seems that the only way to ensure no local can be clobbered,
gensym'ed or not, is to introduce into the RT a local resolution phase
Yeah, I totally agree that using core fns instead of anonymous fns makes
code way more readable and easier to mentally scan. The main reason I
suggested the anonymous function was for performance, which is probably
premature-optimization at this point. But I think I agree with you and Jay,

Thanks Laurent, I did as you suggest and things seem to be fine now. I

Gosh darn... yes, that is what I want. That must be the only
combination of things I didn't try! Thank you.

I'm starting work on a Clojure Web app and would like to get a sense for

Hi,
Random thought from a very tired person. :)
Programmers manipulate tiny pieces of reality, so tiny that quantum effects
come into play. [1]
Many of us (unknowingly) train our visual senses to help us calculate these
strange manipulations with less strain. Maybe if we train it on too

What do you mean by currying in this context? Is there a way to do this in
