Hello,
a quick search of this group, and the web at large, doesn't get any hits
for an Obj-C EDN implementation. Is there anyone working on this?
If not, I'll likely go ahead and implement a basic subset of the EDN spec
for my own needs, which I'd be happy to share.
Cheers,
Matthew.

Just another data point and YMMV, but I've long loved Lisp and long hated

Clojure has a feature called locals clearing, which sets 'coll to nil
before calling reduce in test1, because the compiler can prove it won't be
used afterwards.
In test2, coll has to be retained, because reduce is called a second time
on it.

Couldn't the compiler infer that the 2 expressions are identical with
identical arguments and perform the reduce only once? Basically what the
programmer would do in a let statement? Would that be too expensive?

I have a main project and a subproject and I'm trying to get them to work

Tawny-OWL is a clojure library which provides a DSL for the construction
of OWL Ontologies (http://www.w3.org/2004/OWL/). The practical upshot of
this, is that allows a form of logic reasoning over sets of facts about
the world, with strong computational guarantees about decidability.

Remember, the JVM is a stack machine (before the JIT is run). So the code
produced is something like this:
push coll
push nil
pop-into coll
call-fn red
you can release that on LGPL License ?
does that work with the EPL of clojure ? or is it only an issue when lein

That's funny, I did exactly the same thing and wrote BufferedReader for
both. DOH!
Although I have no idea how the internals of type hinting is, I do think
it's peculiar that there doesn't seem to be type error checking, even
though we are explicitly "defining" the type. I would feel like it sh

You are not defining a type here. A type hint is just that... a hint so the
compiler
can optimize the code it generates to call the readLine method on this specific
object class.
As an example, if io/reader returned an object of a different class at runtime
than BufferedReader, it would not fail
Thanks for the answer Roman!
In the end I went with Matt's lib purely based on the number of stars
and forks - so far so good.

Well, actually Ambrose of core.typed has proposed an interface to let the
compiler know about type information.
That seems to make it conceivable to mark functions as pure, hence,
implement the optimization you proposed, Jim.
Sorry if my first response sounded a tad negative, btw

Hey all,
I've been using clojure.java.jdbc to write a simple database app. When I
use the `update-or-insert-values` function, I get an SQLException thrown
whenever my column names have special characters in them (like a space or
an ampersand). I think the solution is in line 908: the column-str
You can create a ticket for java.jdbc here if you wish that describes the
problem and what you think will fix it. Then any of the 500+ Clojure
contributors can take a shot at fixing it:

Please No!!
I don't think it would help newcomers at all - it takes only a few days to
get used to s-expressions. Coming from a C/Java world I found significant
whitespace in Python to be just as much of a mental leap. And it would
cause enormous confusion if two different syntaxes were in use.
e.g.
(ann test1 (All [x y] [x y -> x]))
where is the 'All' defined?

without looking, I'm thinking maybe it's like "thrown?" when using it for
the "is" macro
(is (thrown? ArithmeticException (/ 1 0)))
where "thrown?" is not defined anywhere and it only has meaning inside "is"
( actually it's *(defmethod assert-expr 'thrown? [msg form]* ... )

Andy's right on process... but as maintainer of clojure.java.jdbc, I
have to ask: why on earth do you have column names containing spaces
or & or other weird characters? That's a serious question: how do you
get into that situation?
I'm not saying clojure.java.jdbc can't be updated to support it,
@Andy: Sorry, I didn't know the proper channel, I'll post it there.
I don't control the column names. They're imported from an excel
spreadsheet or assigned by the client I'm writing the app for. From
experience, it is certainly *possible*, at least to add these columns.
Currently I just have a
