I always assumed (contains? "foo" 2) worked because strings are arrays (i.e.
vectors) of characters, on some level.

You can only safely assume that the first symbol (defn) is a macro, it
turns out 'destructure' is a function called by the macro (which might call

Maybe I should have already known this, but I am struck by this, and I'd
like to confirm it. If I'm working with this code:
https://github.com/drewr/postal/blob/389162cafab08224e50bd6721cac93fe14ca3257/src/postal/support.clj
and if, at the REPL, I do this:
user=> (require '[postal.suppor
Looks good for current project. Project compiles and runs with clojure
"1.7.0-beta3", clojurescript "0.0-3269", figwheel "0.3.1" + core.async
core.match + om + ...
Figwheel repl still works from within Cursive.
Thanks,
Andrew

Well, this is question many people ask. :) It is a matter of tradeoffs:
- Too many arguments may be an aesthetic problem. It may also reflect a
design problem; you might be able to rethink a system to simplify it. (What
"too many" means is debatable.)
- With many arguments, you may c
Clojure 1.7.0-beta3 is now available.
Try it via
- Download: https://repo1.maven.org/maven2/org/clojure/clojure/1.7.0-beta3/
- Leiningen: [org.clojure/clojure "1.7.0-beta3"]
Additional enhancements to new features since 1.7.0-beta2:
1) CLJ-1728 - `source` fn now works for vars in cljc files
2) C
In functional programming you can do a similar thing as in OOP: Define your
functions as closures that can access common arguments via lexical scope.
So instead of creating a context object, you create functions:
(defn make-context [some context parameters]
{:op1 (fn [x] ...)
:op2 (fn [y] ...
Any luck with this? I want to do the same :P

Hi all,
If you have a protocol
(defprotocol Foo (foo [x] [x y]))
and implement it for the record
(defrecord Bar [p q r]
Foo
(foo [x] x)
(foo [x y] [x y]))
you write each method separately. The same is true for extend-type. Yet, if
you use extend-protocol syntax is more like usual Clojure
Hi guys,
when you talk about encapsulation do you mean using defrecords + protocols ?
In this case, we are talking of choosing defrecords instead of plain
functions. Maybe it would be better if we talk too about the drawbacks of
this choice. For example, can we compose or extend protocol functio
