All of our tests are passing with this, so it looks good to me.

I see this too with [org.clojure/clojure "1.9.0-alpha20"] and 
clojurescript, leading to errors in test.js.
I had to revert to [org.clojure/clojure "1.9.0-alpha19"].

Similar to Tommi, I'm also seeing issues with the new syntax when combined with 
JS on our front-end:

[org.clojure/clojure "1.9.0-alpha20"]
[org.clojure/clojurescript "1.9.908"]

This is in the definition of cljs.core.hash. It looks like folks using Clojure 
+ ClojureScript should hold off on using alpha20.

Re: [ANN] Clojure 1.9.0-alpha20

2017-09-08 Thread Alex Miller 
It's a judgement call when to add a new reader type vs when to use a tagged 
literal. Using the new reader type allows for greater concision for sure 
(##Inf vs ##double Inf) which seems particularly useful with numbers. It 
should allow for faster reading, printing, etc.

Relatedly, what is the rationale for this requiring or benefiting from new

Excellent question! The short and possibly misleading answer is yes, as do
all other 1.9 alphas, and 1.8, and probably earlier versions of Clojure as
well *with some important caveats*:

* CLJ-2077 - clojure.core currently uses classes outside the new Java base
module (specifically java.sql.Timestamp for #inst support). This is a
problem if you place the Clojure jar in the bootclasspath, which lein and
(I think) boot both do for faster startup. The lein ticket for this is
https://github.com/technomancy/leiningen/issues/2149. There are changes
being made in lein to allow this to be more configurable. Additionally,
CLJ-2077 is tracking a change in core to defer loading of #inst support if
the java.sql.Timestamp class is not available, which would allow Clojure to
be loaded from the bootclassloader (without #inst support) again. This fix
just missed getting into this alpha, but should be coming in probably the
next release.

* CLJ-2066 - there are some cases where reflection can lead to Clojure
incorrectly invoking a method from a class in a non-visible module.
Avoiding reflection in the first place is probably the best workaround for
this, and turning off various module visibility constraints via JVM flags
is another. We are working toward a more comprehensive solution to this in
CLJ-2066, which I expect to be included in Clojure 1.9.

* Users of dynamic classloaders may experience issues due to the changes in
the classloader hierarchy. This is not really a Clojure core issue, but you
can encounter it through any tooling that uses dynamic classloaders. More
on this here: https://github.com/tobias/clojure-java-9/issues/3

That looks like a cljs issue, it shouldn't emit NaNs at all there, not
relevant to the clojure change around how they are printed.

With 1.9.0-alpha19 it gives:

return new cljs.core.PersistentVector(null, 2, 5,
cljs.core.PersistentVector.EMPTY_NODE, [NaN,NaN], null);

Re: [ANN] Clojure 1.9.0-alpha20

2017-09-08 Thread Tommi Reiman 
Hi.

The combo:

[org.clojure/clojure "1.9.0-alpha20"]
[org.clojure/clojurescript "1.9.660"]

seems to be emitting broken js:

return new cljs.core.PersistentVector(null, 2, 5, 
cljs.core.PersistentVector.EMPTY_NODE, [##NaN,##NaN], null);

With 1.9.0-alpha19 it gives:

return new cljs.core.PersistentVector(null, 2, 5, 
cljs.core.PersistentVector.EMPTY_NODE, [NaN,NaN], null);

regards,

Tommi
