Experience with wisp: 5 years with fewer parens

What changed, what evolved, best practices, usage for a lecture, and why wisp aka SRFI-119 is completed as a language (though not in tooling or documentation).

I have to cancel my attendance for health reasons. Sorry :(. The organizers are informed: Christopher Allan Webber will take over (thank you!).

Let’s do a play with GNU Guile.

        The Jury

Arne Babenhauserheide :enthusiastically:
    I want to present the newest step
    on my path towards the perfect 
    text RPG scripting syntax.

The Jury
    What is special about it?

Arne Babenhauserheide
    It does away with ceremony
    by following the format used
    to write for human actors
    without sacrificing
    any of the power of writing
    in a real programming language.

The Jury
    Did you not hint at a prototype
    of such a system at FOSDEM 2016?

Arne Babenhauserheide
    Yes, and now it works well!

Wisp is a language for Guile which represents Scheme sexp structure transparently using indentation. It makes Scheme look easy for non-Schemers without losing any of its power.

»ArneBab's alternate sexp syntax is best I've seen; pythonesque, hides parens but keeps power« — Christopher Webber

I plan to present its syntax, show some of the elegant solutions with Guile using wisp to make them easy to read, and describe how wisp was cleanly integrated in Guile.

Wisp is specified in SRFI-119.
