Please be careful if you get cold, and decide you need the wool.
I have just done a brief scan (of the @ uses at least) and I think
at least most of them are correct as they are (at least, I did not
see any that are not - but I did not look carefully at every one.)
The man page uses just "@" when it is referring to the name of
the special parameter, and "$@" when it is referring to the results
of expanding that special paramater, so it is correct to say
$@ expands to ...
but would not be to say
@ expands to
as @ doesn't expand to anything, it is just a character.
Similarly,
the special parameter @ gives a list of ...
(or "expands to ...") is correct,. but
the special parameter $@ gives ...
would not be, as $@ is not a special parameter (or
not normally.)
$0 is also the expansion of the special parameter 0,
it would have the same usage rules (though I did not
look for that one - there are far more 0's in the man page
than @'s!)
