When is multiple assignment good style?

[Dirk Laurie <dirk.laurie@...>]

Which of the following uses is in your opinion good style?

- local a,r,k,n = 10000.0, 5.2, 12, 5   -- initializing locals
- local a,r,k,n = 10000,0                    -- initializing only some
- local sort, open, min = table.sort, io.open, math.min  -- caching
library functions
- a,b,c = b,c,a                             -- permuting values
- x,t = x+dx, t+dt                        -- updating related values
- name,cases,fct = "John", {2,5,6},myfunc   -- defining unrelated values
- local a1,a2,[[...,]]a256 = 1,1,[[...,]1  -- trying to crash the interpreter
