both CL and clojure, keeping swank-clojure up to date wrt the slime HEAD is a
good thing, if you ask me. It is, however, a two-way street and I would imagine
that the swank-clojure implementors don't want to spend

A quick aside about matrices. Every dense matrix algorithm is
measured by the number of rows (n). LU factorization is O(n^3), as is
QR. If memory serves, Eigenvalues are usually O(n^2). Determinants
are O(n^3), too. These estimates change if the matrix is banded, they
usually become O(n).

Hey everyone,
I was working with an object that implements java.util.Map today, and

I cam up with this utility fn

Sean,
If the class implements Map, then it already behaves as an associative
data structure in Clojure. E.g.,
(map (fn [[k v]] (println v))
(doto (java.util.HashMap.)
(.put foo bar)
(.put baz noo)))
(get (doto (java.util.HashMap.)
(.put foo bar)
(.put baz

This also works

to use them as functions)
* To get persistence
* To have them print
