Looks like pre defrecord stuff used in early days to add "type" to map. Can
still be used if you need "type" on a map without using defrecord.

Found this:

:tag is applied to source forms to communicate type hints to the
compiler. :type can be used, by convention, to add 'type names' to
runtime data structures that
the type function in clojure.core lets you override the nominal class of an
object with the :type metadata
user=> (type {})
clojure.lang.PersistentArrayMap
user=> (type ^{:type :foo} {})
:foo

Re clj / the built-in repl:

Prints a stack trace of the exception, to the depth requested. If none
supplied, *uses the root cause* of the
most recent repl exception (*e), and a depth of 12.
That is, it
I don't understand what is going on here. I'm trying to throw an exception
with a cause and sometimes the cause is included in the stacktrace and
sometimes it isn't.

Thanks, Alex. I didn't know about *e or Throwable->map.

I am not sure if this is the reason, but I would recommend checking the
command line options used when starting the java process in these cases.
Leiningen uses some command line options by default, for faster startup
times I think, that might affect how much detail is captured in stack
traces when
Thanks. I would not have thought to check that.
These are the processes running after launching each REPL.
$ clj -Sdeps '{:deps {org.clojure/clojure {:mvn/version "1.10.0-beta4"}}}'
Does not include cause.

Reviving this thread, as I'd like to kmow if someone can explain the purpose of
the type metadata and what is responsible for adding it?
