When I see a Swartzian Transform, I think, "Ah! he's sorting the data".
Yeah, but it might take a few brainbeats to notice you're looking at an ST. The sort is bookended between two maps, but not any map/sort/map pipeline is an ST.

If I see: 

    @a = sort {COMPLEX EXPRESSION <=> COMPLEX EXPRESSION} @b

[download]
it's immediately clear data is sorted. Regardless of how complex the expression is, 
    @a = map {$_->[0]} sort {$a->[1] <=> $b->[1]} map {[$_, COMPLEX EX
+PRESSION]} @b

[download]
takes more time to register that data is sorted, and just sorted.

ST's feature is speed. Not readability.
