Hello,
Not a great contribution to the debate, but just a word on the terminology:
reusing package which already has a strong meaning in java may not be a good
idea, I think.
I think lib or library could be interesting, but it has also been attributed
a meaning more similar to "ns description" in

I have about six variables that are often rebound together using
binding; these variables are used to access and set data in a state
object (whose type is of the user's choice). These variables' values
(the accessors and setters) are often used together.
I'd like to be able to bundle these values
Or really work this into core and add :packages to the (ns) macro.

XML is frequently overused, but it is a good format for representing
dense, structured data. For example:
Compared to:

One more thought. I'd change the signature of the second call to
[f init coll]
This matches the original reductions.

It seems to have the same signature, so as a consumer of the library
it's the same to me. If the speedup holds, I say make the change to
your version.
The only warning is that I couldn't find any regression tests for seq-
utils. Perhaps this is a chance to add some.

Ah, very well. I find it useful to print out so I know which code is
doing the logging, since stack inspection is very expensive, and in
the case of clojure, looks like a mess of underscores and dollar

In my case, I don't see the namespace being printed in my log entries,
so I wasn't even aware t
Cache misses are a possibility; try the integer version with long, so the
size of the data is the same as with double.
The other possibility I'd consider likely is that the JDK you were using

Ok, yes, I will blame my idiocy on sleep deprivation.
In every case the name used by the log is the runtime *ns*, which
really defeats the purpose of naming the specific usages of log. I'm
surprised no one mentioned this (imo wrong) behavior.
I'll get to work on fixing it so it behaves properly.

IEEE doubles are typically 64 bit
IEEE floats are typically 32 bit.

What does this return on Windows? (with-out-str (.println
(java.io.PrintWriter. *out*)))
If it's "\r\n", then maybe (newline) should be changed to print
(System/getProperty "line.separator") instead of \newline as it does now.
Thoughts?

Another interesting test: replace the double operation by something longer,

Hello,
I will try to have a guess. If 98% of time is spend allocating Doubles, the
program is loading new lines of memory in cache
every n Doubles. At some point down the different levels of cache, you have
a common cache/main memory for both cores and the bus to this memory has to
be shared in so
