Careful here: [list length] behaves differently in 0.39 and 0.40+!
Better use [list-len], which is the consistent. Similar caution is
necessary when using [urn], which also has two incompatible
implementations. You may want to use urne.pd from RTC-lib, but then
RTC-lib already includes a kind of list-shuffle/list-sample called
scramble.pd

  [list split N]

looks as if it is the same as [list-sample N].
