But I want to add something: I’m getting the hang of just checking the
info-page to look something up. And I realize that with well-written
info-pages this is faster than googling for stack overflow.

I wish I had guildhall ready. Got hit by
time-eaten-by-other-project-because-guildhall-was-priority-three.

It needs to be easy to not just package some code, but also to share
that package without hitting a bottleneck.

A really simple way to share a project would be nice here. Nowadays many
people just push something with a README to github, but github is
unfree.

I never heard that one :)

Or look at py2guile: http://draketo.de/py2guile

Python is no longer easy due to integrating additional syntactic forms,
each of which makes a specific kind of code much nicer but complicates
learning.

We have something similar in foof-loop:

(define (count-matching-items list predicate)
  (loop ((for item (in-list list))    
         (with count 0   
               (if (predicate item)
                   (+ count 1)
                   count)))
        => count))
;       ^^ here

This looks really simple in this place, but it introduces special syntax
which will be unintelligible for someone who does did not explicitly
learn foof-loop.

And guildhall is filled with special forms I had to understand just to
be able to do small changes.

This is a social problem. For a deeper discussion why it is a problem,
see http://winestockwebdesign.com/Essays/Lisp_Curse.html
"Lisp is so powerful that problems which are technical issues in other
programming languages are social issues in Lisp."

We can counter this with easy tutorials and with writing something like
canonical Scheme. But for this, we need to define a canonical Scheme
which is hits the performance and readability sweet-spot for
Guile. Canonical code must be close to the fastest code.

Practically put: We need Andy Wingo to nitpick the tutorial about things
which will cause overheads the compiler cannot fix easily — including
expensive use of macros.

Or because it was the only thing which existed. Didn’t it make it easy
for the hoster to sandbox it — both in terms of access and in terms of
resource requirements?

Sadly not on my cheap webhoster which provides unlimited bandwidth for
a fixed cost.

Or, maybe collaborate with it? I’m sure that there’s lots of stuff which
could be shared, because it is not language-specific (more exactly: it’s
HTML, CSS, Javascript and images).

> What block you from contributing to the wide ecosystem of GNU Guile?

- publishing a program for non-Linux platforms (well, Windows, OSX and
  mobile phones) so most of my friends can use it.

- an alternative to `python setup.py register sdist upload`
