Style question for bar checks

[Noeck]

Hi,

this is a question of ly code style:
Would you recommend putting the bar check always after the note or in
some circumstances also after an including brace?

Background: In many cases it is wrong to put a bar check outside braces
because it is then outside the music expression and appears as its own
music expression. Like:

  \alternative {
    { a2 b } |  % wrong
    { a2 a } |  % wrong
  }

This makes me think one should perhaps always write `a | }`
instead of `a } |` – but how about this case?

  a2 \tuplet 3/2 { a4 a a } |

Would anyone prefer this?

  a2 \tuplet 3/2 { a4 a a | }

Cheers,
Joram


PS: And yes, of course, it does not matter really.
