I have setup VimClojure on Linux, Mac and Windows successfully. (The
classpath stuff is a major annoyance though, and sometimes I think I
have problems with using different versions of clojure.jar.) I also
get large error messages like the above though, which is extremely
annoying. Especially si

This is possible. Since nailgun requires a named class I had to use
gen-class which ties the compiled code relative
Oh, man. I just moved from Seattle to Boston in December, and I miss

Hi all,
some time ago I wrote a simple control library (called "Robust") for

Recently I wrote a Clojure wrapper to the Robust library so that it is

vehicles directly in Clojure.

an easy and very efficient working environment using just vim,

Yup, literal syntax for vectors are very convenient and heavily used
in Clojure code.
And (let) bindings are evaluated left to right. It's analogous to
Scheme's let* i think?
Only thing to watch out for is that (binding) bindings are not
evaluated left to right. It's for performance reasons I thi

Another answer is that ``it could be if you wanted it to be'', for example:

This is from the book:

Hi,all
Although there is no right answer, vector seem to be preferred in many
cases.
Which do you prefer map or vector?
Thanks!

I have confronted a similar question in the past when deciding how to label
the dimensions of vectors and multidimensional arrays.
My tentative conclusion is that it's best to use raw vectors.
=> (def v [40 41 42])
#'user/v
If you need human-readable labels, build a separate index with constant

I concur with Garth - structures like coordinates, points, etc are
non-changing in their structure and hence don't need "mapped"
references into their elements. Destructuring is the easy way to get
at the elements;
