Yes, as I've explained before, in April, 2021, Thunderbird changed from
having a Reply button that sends the response to the newsgroup, to
having a Followup button that does the same thing, and a Reply button
that sends the response by e-mail to the author. I spent a couple of
decades learning to hit the Reply button, and at 66 years of age, after
three years, I'm still finding it difficult to unlearn that habit,
though I've made some progress.

It's not just that it "looks different". It is substantially different
from the First Edition, which had "expression binop expression" as one
of the rules for expression, with a precedence table for binop. It is
also substantially different from the second edition, which closely
matched C89, with a separate grammar production for each level of
precedence. Nor does it look like a plausible intermediate step between
those formulations, which is roughly how you described it.
