Do you know of a reason why (deftype [foo & more]) isn't read in as
having two fields where the second is a seq?
Barring that, would it be reasonable to disallow & as a valid field
name, thus preventing this class of error?

Yes. The docs related to the ns form are indeed insufficient and need attention.
However, have you seen the http://clojure.org/libs
I think there should be a link from the Namespaces page to the Libs
page. Hopefully, this will make it easier for people to find examples
on how to use the ns form.

Dear all,
Currently swank-clojure SNAPSHOT does not show the stack, nor the
exception, on some uncaught exception.
Is it something I can do to inspect the errors?

System/loadLibrary uses the paths set in the System property
java.library.path to look for dynamic libraries so you need to make
sure it contains the directory where your .so is. I think it also gets
cached at first read or something stupid like that so it's very
important to get java.library.path

You can use Visual VM (https://visualvm.dev.java.net/) to see how the
VM is using memory. I don't think it specifically show a log of GC
activity, but it is pretty clear from the graphs.

I think you missed his point. (assoc! m k v) is *allowed* to modify m,
not *guaranteed*. It returns a pointer to a transient map, which may
be m, or may be a totally distinct map, or may be a new map that

Oops, sorry, got my terminology wrong. The sub-arrays represent
*layers*, not levels. So the code should actually read as follows:

(let [size (/ (count blocks) num-layers)

Maybe because Clojure has a vector, and conj conjoins new elements to
the end of the vector, so there's mere little use of fold-right. But,
fold-right is an abstraction tool, missing it in the core is kind of
