[Haskell] ANNOUNCE: Introducing Sifflet, visual functional programming language

[Gregory D. Weber]

Introducing Sifflet -- version 0.1.5, first public release!

Sifflet is a visual, functional programming language. 
Sifflet programmers define functions by drawing diagrams.
Sifflet shows how a function call is evaluated on the diagram.
It is intended as an aid for learning about recursion.

*   A picture explains Sifflet better than words:
    please see the screenshot showing how to evaluate 3!:

*   Features:
    -   Visual editor.
    -   Visual tracer/debugger which shows how function calls are
        evaluated -- including recursive calls, of course.
        -- This is an active learning process: Sifflet doesn't
        overwhelm students with a huge trace of function calls;
        it provides only as much expansion as the student
        requests.
    -   Extensive tutorial with 6,348 words and 31 pictures -- 
        so hey, it's worth 37,348 words!  (but not 37,348! words)
    -   Number, string, and list data types.
    -   Palette with a small number of primitive functions.
    -   Runnable examples of compound functions.
