Hmm...still not.
If you want (...) to mean "the pattern that matches a list ..." then you
need a backquote in front:
`(foo bar) matches a list containing the symbols `foo' and `bar'.
`(,foo ,bar) matches any two-element list.
The intuition is that the pattern matches elements that could be the
result of evaluating an expression of the same shape.
