in reply to When the Best Solution Isn't
Aside from not being a fair shuffle (8 paths mapped to 6 end states) I believe it can actually cause older perls to dump core.@random = sort { .5 <=> rand(1) } @array; # DO NOT USE THIS!
Sorting assumes a transitive ranking function... If A > B and B > C then A > C. Returning random numbers for your comparison results wont comply with this requirement, and can wreak havoc depending on the internal sorting implementation.
