Exactly because you are actively trying to understand the syntax, you
are in unique situation where you can easily see all the "opaque"
places
in the syntax description.
I still don't know if I misunderstand the syntax description document or
if there is really and "error" in it.
That's why I ask you to propose modifications
to the document that would make it easier to read for you.
First of all I have to understand everything and then write that down
for my self (especially as Python code and unittests).
My english is awful and it wouldn't help you. I even do not understand
all words and sentences (from a language perspective) of the syntax
description document. I am not into it enough to propose a patch. I can
only offer you "my understanding" of the document and "testing" a new
version of it.
