The curse of the trivial example. Would you agree that first is a lot easier on the eyes than the latter two?:

print "And the set contains [ { sort @a } ]\n";;
And the set contains [ brown dog fox jumps lazy over quick the the ]

printf "And the set contains [ %s ]\n", join ' ', sort @a;;
And the set contains [ brown dog fox jumps lazy over quick the the ]

print "And the set contains [ ", join( ' ', sort @a ), " ]\n";;
And the set contains [  brown dog fox jumps lazy over quick the the  ]

Even with the complication of the p5 syntax, it's still nicer to my eyes:

print "And the set contains [ @{[ sort @a ]} ]\n";;
And the set contains [ brown dog fox jumps lazy over quick the the ]
