In this example
(defrecord x [y])
(defn b [x] (.getBytes ^String x))
The compiler fails to resolve .getBytes. It emits reflection code, saying x
is a class. It is resolved by deleting the defrecord, or renaming the
parameter.
Is this expected, or documented? Are there other cases like this?
Is there any way to inspect what the jit does to it?

The transducers doc suggests transduce works with standard reducing
functions, but then transduce makes a one-argument call to the function.
The code docs for transduce say the reducing function must support a
one-argument call, but don't give any information about what that call
should do.

Probably more of a java question, but I'm finding that floating point
formats with (format) are inflating data sizes enormously with meaningless
trailing zeros, because the underlying java conversion methods don't work
as they do on other platforms.

printf("%.6g %.6g %.6g %.6g\n", 0.

Trying to eliminate a reflection warning, I put a type hint on a function,
like
(defn foo ^PStatement [] ...)
which compiles without the reflection warnings, but at run time I get
ClassCastException java.lang.ClassCastException: cavm.h2.PStatement cannot
be cast to cavm.h2.PStatement

In need of a way to breakpoint in java code, I decided to look at intellij.
I tried the directions here:
http://wiki.jetbrains.net/intellij/Getting_started_with_La_Clojure
which don't work. When trying to open a project, it throws:
java.lang.NoSuchMethodError:
com.intellij.openapi.module.Modif
What clojure tools should I be considering for doing syntax tree
manipulations? In general, I'm recursively matching patterns in subtrees
and rewriting them. The patterns are usually more complex than, say,
core.match patterns (e.g. match subtree having vector that contains term,
and split the
uture invokes the binding conveyor, which sets *err* to the vim
channel. Where does Thread get its *err*?

A small clue, gleaned from a cider issue:
This outputs to the repl terminal.
(future (.start (Thread. #(println "blah2"
This output is captured by vim.
(future (println "blah3"))
Still no idea what's going on.

Still not able to track down stderr. Anyone know how this stuff works?
Dumping *err* from a ring handler, running from jetty, I get
this: java.io.PrintWriter@1d9e436a. This will write to the repl terminal,
so long as I flush (wtf... stderr is buffered?).
If I dump *err* from a future, I get th
Running a ring server from vim-fireplace, any errors that occur during
request processing will dump to the repl terminal, which is fine. I'd like
to add debug output and have it also dump to the repl. However printing to
stdout or stderr from a ring handler doesn't work. How can I output to the
I'm sure I've seen a thread on this, but can't find it now.
Is there a common pattern for sending management commands to a running
server via cli? E.g. if "foo" starts my ring server, I need something like
"foo -x twiddle" to send "twiddle" to the running process.

I came across this today in a library:
results (seq (doall (filter modified? files)))]
I believe the seq is to coerce the empty list to nil. What is the doall for?
