Thanks for the warning, I had no idea!

I may have changed over time - it did not bounce now. Check with David R. Linn <[EMAIL PROTECTED]>.

(don't reply to this email, then)

It is sort of automatic, when doing reply-to-all. Easier to not worry about the bounces. But the one that put up the cc may not get the intended effect.

I find them quite useful in another project I maintain; should we use
them throughout the LilyPond docs?
I think you might more words, depending on the contents.

For clarity of documentation writers, I've defined a single @warning {} macro, so we can only pick one word. Everybody likes "note", so I've gone with that.

That is probably more normal in documents. The Bourbaki used a "dangerous bend" symbol, and Knuth in the "TeX book" used something like that to. So I think that the important thing is to get a clear classification whatever it is. Knuth uses a dangerous bend symbol in a road sign symbol. Perhaps an exclamation mark "!" could be used for information that is required for the code to compile.

Now, the first part is really a requirement:
Every part of LilyPond input must have curly braces placed around the input - or else the compile fails. So it is not merely a warning - it is a requirement. Also, I changed "piece" to "part", following Church's book on lambda calculus, which has a technical definition of a "part" of a lambda expression. It seems me, you have a similar syntactically closed part in mind here.

Speaking non-technically (I've never read any of Church's writings, and I've forgotten his famous law/thesis/something on formal automata), I think that "piece" is better than "part". "Every piece of..." sounds more natural than "Every part of..."

If this was in the user manual, I'd be tempted to go with the more technically correct word (ie "part"), but the tutorial is designed to be easy to read, so I prefer keeping "piece".

Right. "Piece" is better informally; "part" would you ever decide to give a technical definition.

And if they are omitted in the manual, is it because there is an error in the manual or what?

This is explained in 2.1.4 How to read the tutorial.

Then perhaps give some hint of that :-). If there should be a comment at all, it might be reworded as say: "as mentioned [before|elsewhere| in section 2.1.4], required [spaces|braces|stuff] may be omitted in the examples". This style makes the text somewhat heavier, but it helps local reading.
