Deal! :)

Fantastic! I can write some of the basics. 

An introduction and a couple of examples of use to the higher-order
functions like fold-packages would be nice I think.

Also a chapter on befriending with the guix repl would be nice. I had
some eh, troubles with it in the beginning (and sometimes now) because
it is not clear to me when the earlier loaded procedures are cleared.
ATM my workflow is like this:
inside screen
open emacs with the scheme file i'm working on
m-x 3
m-x shell
enter code in the scheme file
m-x o
run $guile in the dir of the file
(load "file.scm")
(test-some-proc)
m-x o
enter code in the scheme file
m-x o
run $guile in the dir of the file
(load "file.scm")
(test-some-proc)
...

Sometimes I have to quit guile and reenter to get it to work right (if I
change some names of procedures and forget to call the new ones. (this
happened 2 times during devel of guile-wikidata) 

Also I found 2 bugs I think (I have yet to report them).
1 where paredit-mode would not move the last parens of a proc when
commennting aout sub-parts of that proc.

1 where run-guile -> geiser-eval-buffer fails to eval the buffer
(resulting in me resorting to the suboptimal IDE above).
