To produce a pair of values in Scheme, you should write
\override TupletBracket #'connect-to-neighbor = #'(#f . #f)
(another option is the following:)
\override TupletBracket #'connect-to-neighbor = #(cons #f #f)
See the documentation of edge-height and shorten-pair for other
examples of pairs of values, that show this syntax.

Quoting Marcus Macauley <[EMAIL PROTECTED]>:
As far as I understand, the following four overrides:
\override TupletBracket #'connect-to-neighbor = #'(#f #f)
\override TupletBracket #'connect-to-neighbor = #'(#f #t)
\override TupletBracket #'connect-to-neighbor = #'(#t #f)
\override TupletBracket #'connect-to-neighbor = #'(#t #t)
documented at:
http://lilypond.org/doc/v2.9/Documentation/user/lilypond-internals/TupletBracket.html
should result in the following four bracket designs, respectively:
|-- 3 --|
|-- 3 --
-- 3 --|
-- 3 --
But I find that the second of the boolean pair has no effect (as if
it were always #f), so the four overrides above result instead in
the these four bracket designs, respectively:
|-- 3 --|
|-- 3 --|
-- 3 --|
-- 3 --|
Below is a file which demonstrates this. It uses triplets like:
\time 2/3 {g8 g4}
But I also tested it with:
\times 2/3 {g4 g8}
and the effect was the same.
Let me know if I'm doing something wrong; as far as I can tell, this
is a bug.
Thanks,
Marcus

% Asterisks (in the markup) indicate the places where bracket ends
are drawn incorrectly.
%
% The 1st system tests each possible boolean pair followed by
(#f #f);
% the 2nd system tests each possible boolean pair preceded by
(#f #f)
% The 3rd and 4th systems do the same for (#f #t).
% 5th and 6th systems: (#t #f)
% 7th and 8th systems (#t #t)
%
% The markups for those pairs which are being tested, are
capitalized;
% hence, "F F" for the 1st and 2nd systems, "F T" for the 3rd and
4th systems, etc.
