The :fill option gets a brief mention on page 10, but I didn't spot it
anywhere else or being used in an example:
There is also a general C:fill option that sets the default sequence
for any filling that isn't otherwise specified.
That suggests there's a hierarchy of options like this:
The C:page{:length} sub-option (page 12) is described in the text as
having a default value of infinity but in a comment in the example above
of being 60. How so?
Is that the text normally isn't split into pages at all (so effectively
giving a single page of infinite length), but as soon as
OK, I've given up on having completely separate mails and thrown
together a bunch of small points. Some of these are pointing out typos;
I mention them not to complain, but in case anybody's bothered about
correcting them to avoid future confusion.

First, thanks Damian for doing this, and good show!

here are a few others I noticed:

I think the claim in E7 is stronger, that not only does the string match
the identifier pattern, but that it is a 'valid' (known, declared)
identifier. Else, what would be the point of saying both:

* check the validity before the program starts

So, what I'm looking for is more explicit phrasing around immediately
above. In the example, the column range for the overflow field is
exactly the same as that of the $method field in the prior picture.
But, what does it do if it doesn't match *exactly*? Is it an error,

Correct.

Race condition. That is, I'm racing to get it out. That process is being
