in reply to Swapping keys and values in a hash with slices

This seems reasonable enough to me, with the usual caveat that you will lose information if multiple elements share the same value.

I would never use this code in production, though. You mention other solutions using loops and map, but I find the %revhash = reverse %hash idiom more elegant.
