There I was, encoding a japh, when i realised that the key I completely randomly picked might actually be useful: 
s//6a06e920-61f00961-6f100170-72075274-00968d65-65774473-00e00363-2056

+sh@{++$c
%2?a:b},$c%2?chr hex:$_ for/(..)(.)/g;print map(splice(@a,hex,!/-/),@b
+),@b,$/;

Imagine my surprise!

I'll leave it as an exercise for the reader to discover what it's useful for....
