I'm not sure why you write "finally" here; I'm not even sure I can remember
any ChucKian paper that *didn't* make this very clear, correct me if I'm
wrong but I think this was explained in the early papers already and hinted
at in the old priority lists and so on.
I think this is a good choice, not just for novice users. Aiming something
too much at the novice is -IMHO- a bad idea as people will only be a novice
for such a short time. It's quite often that we see people sign up to the
forum, ask how to get running at all and within a few days come up with a
quite functional musical toy/tool. I'm not sure I'd call people "novice"
after that any more.
Being very readable is good for everybody. It's good in situations that are
high on stress and/or beer, it's good at 3am and it's good for resuming work
on a complicated project after a month or two. Basically it's good for all
of us. I'm personally convinced clear language can/could save us all a lot
of confusion and disagreements, often even arguments. Sadly in real life we
are stuck with natural languages so some confusion there is unavoidable
A few days ago I walked for a few extra Kilometers because the directions I
got stated a certain road would "turn into" another. I took "turn into" to
refer to "change into" while what was meant was that I could take a "turn"
into this other road. Clearer directions would have saved more time there
than a bike could've.

I think I'm fairly aware of the sort of thing you are trying and doing and
I'm not sure I agree what you are fighting is a actual language issue. IMHO
the more relevant question there at this moment is some bad bugs and a lack
of documentation. I'm thinking about the type system and casting in
To me those are age issues (and developer time constraint issues) more than
real language design ones. As you know very well; ChucK as a program doesn't
always and everywhere follow ChucK as a language specification. Mostly the
difference is pure bugs. Right now I feel that the problem with (very)
advanced code is that -so far- relatively few people write it and so once
you start doing that you'll run into a relatively large amount of bugs.
This makes such code hard or sometimes even impossible to write but to me
that's a bug issue and not a language one.

Agreed. Well, agreed as long as additions are made in a way that's coherent
with the rest of the design. So far ChucK syntax is quite coherent and that
in itself makes it easy to write.
I too would like things like functors and i'd like (chuck-) operator
overloading but not at the expense of coherence.

This is clearly great.

Wow, how did I miss that? That looks great!
Not at all, it all seemed quite coherent and sensible to me, even if I
didn't agree with every point you made.
