Hello,
I noticed that srfi-19-date (version 3.3.4) does not export 'date?'. I
think that perhaps it should. Also, 'date?' is not documented in the
egg docs (http://wiki.call-cc.org/eggref/4/srfi-19).
Thank you,

Hello,
Has anybody used the color egg to do colorspace conversions? I'm
getting some unexpected results, and wonder whether there are bugs in
the egg, or whether I just misunderstand something about the colorspaces
involved.
Here are the relevant links:

Hello,
I ran into a little problem when working with the r6rs-bytevectors egg,
which provides an r7rs implementation of (r6rs bytevectors). The
bytevector-copy! procedure has a different call signature in r6 than in
r7, and I found that as r6rs-bytevectors is currently written, its
bytevector-cop

Hello,
What is the recommended way to perform complex initialization of object
instances in coops? Say I need to initialize a certain slot based on
the values of other slots in the object. Is the initialize-instance
generic designed in a way that it is safe to do something like this:

Hello,
I'm writing a program that uses xlib and have hit a question that I
cannot make heads or tails of from the web docs. I have a procedure
that takes a window and a list of numbers and sets a property on the
window which is an array of those numbers. The array must be an array
of unsigned lo

Aha, thank you. Yes.

There seems to be an error in the documentation for zip-alist. Possibly
due to a syntax error in the source?

Hello,
I have a feature request for spiffy.
The background: I set up an awful-based web app behind an apache2
reverse proxy. Awful/spiffy is listening locally on port 8080, and
apache2 delivers requests to it via mod_rewrite with the [P] (proxy)
flag.
Under this configuration, the spiffy call (

would like to make this a feature request. When running chicken-install

Hello,
I am using chicken 4.7.0, and in the course of writing some library
bindings, I came upon a difference between define-foreign-type and
define-foreign-enum-type that puzzles me. Here is a minimal program
that shows it:

typedef enum
d pointers to any foreign type (as it's just a
