Is there a simpler way to do this with higher order functions like map and grep?

Of course you can transform a for-loop into a map/grep construct, populating the return value \%output in one fell stroke (why isn't that a reference in the first place, if that is what is returned?) - but I doubt you would save significant lines of code, or improve readability. Job well done, move on :-)

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
