Okay, I did it. Check out the attachment. Bit of advice: it wasn't designed to be "elegant" as in "ooooh!" :-) It was designed to "feel right" for someone coming from C or (to a lesser extent) Python.

This is interesting. I never cease to be amazed how hard it is for some people to grok Smalltalk syntax, once they have been exposed to C. I find this with professional engineers, and with high school students.

I have one suggestion for the declaration syntax. The colon is not particularly C-like. C programmers would write "int x". Of course, you ChitChat doesn't have types, but you might adopt the idea of using a keyword. So, instead of

to:do (1, 8, {:(x) y: y = nextInt (myrandom, x); plotBetween:and (self, x, y); });

you might try

to:do (1, 8, {param x; var y; y = nextInt (myrandom, x); plotBetween:and (self, x, y); });

This means that binary messages param: or var: can't be sent, but if one needs to do that, one can always use perform:with: as a workaround.

Incidentally, C uses double quotes for strings, and single quotes for characters, so it probably makes sense to adopt that convention.
