Good !
Do you consider putting this on the clojure wikibook ?

Hi Josh,
As a general recommend
So there's a different macro analogous to "String." for a bunch of different
classes, and it doesn't work for arbitrary classes?

It works for arbitrary classes. Any symbol that ends with a dot
macroexpands to a 'new form.

Thinking about it again,
Is qualifying this as a non-bug, a known limitation the best that can
be said about it ?
Could the implementation be improved to handle this case, or is there
a theoretical reason I've not thought about that prevents doing this
for the general case ?
Thanks,

I'm pretty well a complete beginner at clojure, but I was hoping I

Emeka,
Your 'file' is an actual file. What you want is it's name. I think
the last line should look like this:
(println (str "file " (.getName file)

Hi, I've been playing with nio lately and it's been quite fun to delve
in lower level stuff again, didn't do that in a long time. I've
translated a small example, just to read a file, and the result is
performing really well. Here's the code:

Hmmm... I just tested this in Enclojure. use works fine there.
Still doesn't work on my Aquamacs/SLIME setup. I'll check my config.
