No. In section 3.2.1, see the productions for
<character name>. In section 3.2.6, note that
#\linefeed and #\newline mean the same thing.

That's pretty funny. Fortunately, the CHANGES
document is not intended to be normative.

Here's one that caught my eye:

- extended `flexpt' for negative fl1 if fl2 is an integer

Note that fl2 must be a flonum, so it cannot be
an exact integer. I think this change is for
the worse. The use of "integer object" in the
specification is an especially misleading phrase.

In general, I am less unhappy with the changes
that were made than with the changes that weren't.
It will be interesting to see what they propose
as a candidate for ratification.

The rationale document also contains some, uh,
"artefacts" that help to explain the report's
"datums".
