Hi,
I have a scenario where I have two records:
(defrecord Foo [a b])
(defrecord Bar [a b c])
You will notice Bar has only an attribute more than Foo. Both Foo and
Bar are data abstractions where Foo is a subset of Bar.
Now, when I try to construct a Bar from an existing Foo instance, I
get thi

Have you tried this?

#user.B{:a 1, :b 2, :c 1}

Pretty cool – thanks! Didn't know about map->

Hi,
your comparison is not fair. The map example merely assoc's a new value,
while in the record case you create a complete fresh value with a different
type. Here some more comparisons:
user=> (defrecord Foo [a b])
user.Foo
user=> (defrecord Bar [a b c])
user.Bar
user=> (let [x (->Foo 10 20)]

It occurs to me that these sorts of optimizations would need to tunable.

I've been *mostly* ignoring that file, since I haven't had to change it yet

You could always piggy-back on Leiningen user-level profiles.

Hi All,
I'm not sure if this has been asked before.
I followed the quickstart guide:
https://github.com/clojure/clojurescript/wiki/Quick-Start and did
git clone git://github.com/clojure/clojurescript.git
cd clojurescript
./script/bootstrap
Then I tried
rmc-235-244:clojurescript seanneilan$ ./sc
Did you try using lein-cljsbuild (together with the instructions on
Using Clojurescript in a Web Page on Quick Start)? That works fine
for me. The instructions on the lein-cljsbuild REPL are here (repl
listen should be enough to get you going):
https://github.com/emezeske/lein-cljsbuild/blob/0.1
sounds like you didn't set CLOJURESCRIPT_HOME or that it was set
incorrectly.

Thank you so much!
I'll submit a patch to the documentation.
