Also, pop throws an exception on the empty list whereas rest returns ().

see some of my Clojure work on github (github.com/ECAllen). I also have
private repositories with more Clojure work.
If you are interested my skype name is ethan_allen_

I think it's important that Clojure be good at exploring Java
libraries. Helpful and correct error messages are important for this.
I often go looking for a function at the REPL, like so:
user=> substring
java.lang.Exception: Unable to resolve symbol: substring in this
context (NO_SOURCE_FILE:
Makes sense, but (#{:a :b :c} :b) doesn't return 'true', it
returns :b. So it's not really acting like an object to boolean
mapping. Doesn't much matter, though.
By the way, I'd like to see map-map in the core.

Then why are sets callable? Not that I'm complaining - I found it
handy, then came to wonder why lists aren't.

Why aren't all sequences callable, i.e. why don't they all implement
IFn? I'd like to use lists like this sometimes.

Right, the outer parenthesis denote a list. That list contains only
one element. The element is the vector ["qui" "ui" "i"]

It's very handy to be able to type in a symbol at the REPL and see its value.

Seconded. As far as I can tell all you can do is go to Sourceforge
and poke around in the source code:

For the File / IO things, skip the Java libs - they are pretty low
level. Go with the Jakarta Commons libs:
http://commons.apache.org/io/description.html , as Stuart has
recommended elsewhere.

Has the inverse of slurp been added to the core libraries yet? Like this:
(spit "Some text" "/foo.txt")
to make a file called 'foo.txt' containing "Some text".
By the way, it appears that Clojure (or Java) doesn't recognize ~, as
in (slurp "~/foo.txt"). True?
