Samppi,
Here's a parser-m monad I did.
(defmonad parser-m
[m-result (fn [x]
(fn [strn]
(list x strn)))
m-bind (fn [parser func]
(fn [strn]
(let [result (parser strn)]
I sympathize with your difficulties, but isn't there something
fundamentally incompatible between the later-or-never of lazy-seq and
the this-way-here-and-now for which dynamic binding is good for? In
this case you picked laziness over code simplification, maybe it'll be
the other way around some
Yes, your monad was the first monad that I was talking about—in fact,
I followed your tutorial when I was learning about monads, and I used
your examples to create an entire parsing library. I believe that it's
essentially equivalent to (state-t maybe-m), except that you use list
pairs instead of

Hi,
a short discussion on the SLIME mailinglist lead to the result that
the arglist of a backend function in swank did change.
Current checkouts of SLIME do not work with Clojure, at least if you
use autodoc.

One place where interop needs improvement: imports.
This is ridiculous:

Regarding Clojure sequence functions: why couldn't they have the
option of returning non-lazy seqs? Because you don't always really
need lazy seqs. It might be nice to have the option.
(map (fn[x] x) [1 2 3] :strict) - [1 2 3]
or even
(binding [*strict* true]
(map (fn[x] x) [1 2
It might be nice to have the option.
You do -- wrap the form in doall.
(binding [*strict* true]
(map (fn[x] x) [1 2 3]))
would be equivalent to
(doall (map identity [1 2 3]))

I'm not actually complaining, but I do notice every single time I fire
up a REPL. The more code that you have, the longer it takes.

Alternatively, force (or at least allow!) square brackets, like

Other part of that explanation is whether x in a given piece of code
