'(something) is just an abbreviation for
(quote something).
This is not correct.
'(something) ≡ (quote (something))
which evals to a list of one element, the symbol ‘something’
i.e., => (something)
but
(quote something) ≡ 'something
which evals to the symbol ‘something’
i.e., => something
Also, i think it's better to say "evals to" rather than "returns".
The latter strikes me as indicative of a function-call context.
OTOH, ‘eval’ is a function, so i suppose YMMV... :-D
