I hope I got this right:
For Lists, syntax-quote establishes a template of the corresponding

From a practical position, anonymous functions of the #(+ 5 %) flavor
*are* partial application. The ubiquity of these anonymous functions
in clojure code is evidence that partial application is just as needed
in clojure as it is in haskell. #(+ 5 %) is not much more succinct
than (\x - x + 5).

Thanks Konrad.
I certainly do not want to add this to fmap. However, I think there
are lots of situations where mapping keys is well-defined. For
example, you have a tree of data from XML or JSON, and you want to
replace the keys (strings) with instances of their actual type.
I guess

I'm not sure if this is an issue or not. I broke it down to a simple
case. When I pass a Java object into a map closure the object doesn't
seem to get updated:
(let [b (new StringBuffer)]
(map #(.. b (append (str % ))) '(blah blah blah)) b) ;=
#StringBuffer
expected ;= #StringBuffer blah
Dex,
Thanks for the info. It's nice to understand what's going on. I am
trying to dig into the source more to get a deeper understanding of
the language, but Clojure is my first exposure to Java, so that part
is slow going.

Uh, yeah you can. Haskell can have variadic functions, like

still partially apply it.

Lazy evaluation strikes again! map doesn't actually do anything until

If you are using the REPL the return result is the lazy-seq, and this

As for doing bounds checking during (int), I think that would be a net
