you can use `set!`:

{
  \afterGrace c' c' \break
  #(set! afterGraceFraction 999/1000)
  \afterGrace c' c' \break
  s1
}

But note that this may cause race conditions, and `afterGrace` allows 
specifying the ratio as optional first argument. In this sense I would deem it 
safer to use that optional argument over going around changing the default all 
the time.

Valentin
