Yes, thanks.
PaddleGuru.com isn't open source, so I can't share any of the

Looking forward!

A couple of things on this subject:
1) protocols were invented primarily for their speed. If one was going to
write Clojure in Clojure it would be a little hard to implement
PersistentHashMaps using pure data. You have to start with something. Thus
deftype and defprotocol were born.
2) Unlike in
Consider the following two code blocks:
(ns util.core
#+clj (:require [clojure.core.async :as async]
[types])
#+cljs (:require [cljs.core.async :as async]
[types])
#+cljs (:require-macros [cljs.core.async.macros :as async]))

finds dates, and other data types, heuristically -- I'm sure Google would
rather not, but that's life on the web.
Google also supports JSON-LD which is a W3 standard for semi-structured and
linked data. JSON-LD defines in-band syntax for dates, all XSD data
types, and arbitrary data types
can you elaborate on #3? What constraints did you run into with
type-based dispatch that a multimethod that dispatched on :op allowed
you to get around? It seems like, if that's your pattern, lifting the
:op field up into an actual record type would only give you MORE
freedom. You rely on the
If you implement an API returning custom types or records, consumers
will have to adhere to the same implementation in their own implementations,
The so called freedom becomes a cage for others, they are stuck
with your implementation and it leaks out in places were they should not.

Is it likely that a typical Clojure development environment:

I'm curious for the response re: #3 as well, but one pain point I've
experienced with protocols vs multimethods is that as a system evolves,
retaining the semantics that led me to bundle functions together into a
protocol in the first place has sometimes been difficult, a source of
incidental
Good points about the graphics, Tim. Do you have any idea if the JVM's
RAM requirement in itself takes more power from the system than
developing, say, a Rails app in Vim? One pisser with my new-ish Macbook
Pro is there's no such thing as a spare battery.

Consider this piece of code:

From this, it follows that binding and async/go do not work together
(probably due to the go block running in another thread).

Hi,
Does cljs provide anything like format?
I do not need it to provide the same output as clojure's format.
I just want to write things like:
(format ... % ... % ... % ... arg1 arg2 arg3 )
rather than:
(str ... arg1 ... arg2 ... arg3 ...)
Thanks!

It's worth noting that the - and - macros are just that: macros. They
have lexical extent and are expanded at compile time.
Factjor is (essentially) interpreted, but can be used in interesting higher

Is there an official site listing Clojure study-groups / meetups?
In particular, I'm looking for one close to Stanford (i.e. wouldn't mind

over lunch / dinner.
Thanks!
There is this list of Clojure user groups:

You can go to meetup.com and search for Clojure. There are several
meetings per month in the Bay area, in San Francisco and San Mateo, usually.
There is also the #clojure IRC channel, which
