Did you run the benchmark several times? Such small differences are suspicious. It might be more enlightening to use a perl binary with -DDEBUGGING and dump the parse tree. For well implemented variations of syntactic sugar of the same thing I'd expect the the compiler to produce the same tree.

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