Re: [ANN] Clojure 1.10.0-RC1 (please test!)
You might want to add to the datafy ns and function that they were
introduced in 1.10. I noticed they didn't have the :added metadata that
most Clojure core stuff has (it's very handy in IDEs/starter editors).

RE: [ANN] Clojure 1.10.0-RC1 (please test!)
RC1 seems to be doing just fine in dev/test for us (83K lines of code,
including tests). We have Beta 1 in production on one server and Alpha 8 on the
other four servers. No problems with any of that so far. I expect to have RC1
on all our servers next week.
And we’re happily taking advantage of ex-message now in our code

Re: [ANN] Clojure 1.10.0-RC1 (please test!)
I ran the latest version of Eastwood on the Clojure code itself, and didn't find any surprising/new warnings. There are a fair number of reflection warnings in what I would consider non-performance-critical functions (e.g. clojure.java.browse/open-url-in-browser, and code for handling/printing exceptions) that are not new. There are also what I think have always been reflection warnings for things like aget/aset that I don't recall digging into before -- Clojure code for that stuff hasn't changed in quite a while, so I can't see that is anything new. I made some preliminary updates to the Clojure cheatsheet in preparation for the 1.10 release, and noticed that the new Var clojure.main/ex-str does not have any :added "1.10" metadata for it, but many other Vars in clojure.main also do not, so perhaps that is intentional. I will try a full run of Eastwood on a set of 80+ open source projects with Clojure 1.9.0 and 1.10.0-RC1 soon-ish, and see if anything surprising comes out of that. I've done it with 1.10.0-beta1 and didn't see any issues, and don't expect any problems.

Prototype code for enhanced CIDER code completion for Java methods
I'd like to share an idea and prototype code for better Java code completion in
CIDER. While my main development environment is CIDER, the small modifications
I made to support this idea were both to cider-nrepl and compliment -- which
are both used by other Clojure tooling besides CIDER -- so maybe this is
immediately more widely applicable.
In an effort to make it easier on the tooling, I'm using a slightly different
syntax for calling Java methods. My inspiration is Kawa scheme, and the
notation is very similar:
(String:charAt "my-string" 0) => \m
(Integer:parseInt "12") => 12
(possibly.fully.qualified.YourClassName:method this args)
For this syntax to be properly compiled of course it needs to be wrapped in a
macro:
One form:
(jvm (String:charAt "my-string" 0))
Any number of forms:
(jvm
(lots of code)
(JavaClass:method ...)
(more code)
(AnotherJavaClass:method ...))
The jvm macro will transform any symbol it finds in the calling position of a
list that follows the ClassName:method convention. I was thinking maybe of
limiting it to just a particular namespace to absolutely prevent any name
collisions with real clojure functions, something like:
(jvm/String:charAt "my-string" 0)
This will also work with the one-off test code I'm including here for folks to
see what they think.
I actually like the syntax (though I wish I didn't have to wrap it in a jvm
macro -- though if this actually idea was worth fully implementing, I'd imagine
having new let or function macros so you don't even have to sprinkle "jvm"
macros in code much at all).
There is one additional advantages to this style of Java interop besides the
far better code completion:
- The jvm macro uses reflection to find the appropriate method at compile
time, and as such, you get a compile error if the method cannot be found.
- This is a downside if you *want* reflection, but this of course doesn't
preclude using the normal (.method obj args) notation.
You could even use this style for syntactic sugar for Java method handles:
- Though not implemented in my toy code here, you could also pass
String:charAt as a clojure function -- assuming there were no overloads of the
same arity.
So, I'm hoping you will try this out. Two things to copy/paste -- one is a
boot command, the other is the 100-200 lines of clojure that implements a
prototype of this.
This command pulls the necessary dependencies as well as starts up the
rebel-readline repl (which is fantastic tool, and it also uses compliment for
code completion):
# Run this somewhere where you can make an empty source directory,
# something fails in boot-tools-deps if you don't have one
# (much appreciate boot-tools-deps -- as cider-nrepl really needs to
#be a git dep for my purpose here since it's run through mranderson for
its normal distro)
mkdir src && \
boot -d seancorfield/boot-tools-deps:0.4.6 \
-d compliment:0.3.6 -d cider/orchard:0.3.1 \

Re: [ANN] Clojure 1.10.0-RC1 (please test!)
Congrats!
Small suggestion. Under dependency updates it would be helpful to see the
previous version eg
"spec.alpha dependency to 0.2.176" -> "spec.alpha dependency from X.X.XXX
to 0.2.176"
