 \relative c' {
  \set tupletSpannerDuration = #(ly:make-moment 1 2)
  \times 2/3 { c8 d e f g a g f e d c d }

% The tuplet brackets last a half-note, but the beaming remains 
% in quarter notes, because the tuplet bracket is independent of beaming

% Below, there seems to be a typo; do you suggest a warning should issue?
% There are 12 quarter-notes grouped into triplets, which would seem to be 
%  properly grouped in 3rds of a measure.

  %  \set tupletSpannerDuration = #(ly:make-moment 1 4) %% typo
  \set tupletSpannerDuration = #(ly:make-moment 1 3)  %%corrected
  \times 2/3 { c4 d e f g a g f e d c d }
 }

The fact that there are ways to use a feature without getting useful output,
is not surprising.
