Do make sure certain chores get no prevalence over other chores, association-wise, I made a little worklist randomizer.

Lets say I have a number of chores in a list:

 set w {
  {washing up}
  {cut the grass}
  {shave (very important!)}
  {watch CNN}
  {finish some Tcl programs}
  {work in computer field}
  {buy tickets in a lottery}
  {go voting (even more important!)}
  {etc (whatever else comes up)}
 }

Now we want a random iten from the list, or a random permutation of the list, with no priorities:

 lindex $w [expr int(9*rand())]

Of course we could do the same with the rest of the list.

[Googie] 17.09.2008 - I'd upgrade method of retrieving random entry:

 lindex $w [expr { int([llength $w]*rand()) }]

But there is still missing solution for removing from list jobs that are already done. So we need a procedure for that:

 proc lremove {varName idx} {
     upvar $varName lst
     set val [lindex $lst $idx]
     set lst [lreplace $lst $idx $idx]
     return $val
 }

and finally:

 lremove w [expr { int([llength $w]*rand()) }]

[TV] I had made this:

 proc randout l {
    set i [expr int([llength $l]*rand())] ; 
    return [list [lindex $l $i] [lrange $l 0 [expr $i-1] ] [lrange $l [expr $i+1] end ]]
 }

This is a list shuffler which can be made recursive, but it escaped me how to make a flat combined list...

( Example:
(Tcl) 62 % randout $w
{go voting (even more important!)} {{washing up} {cut the grass} {shave (very important!)} {watch CNN} {finish some Tcl programs} {work in computer field} {buy tickets in a lottery}} {{etc (whatever else comes up)}}

)
