I tried again now and there is of course a little impact: About 1.5% 
(average speed for five tests of each). We could use both versions in 
the future if we like to but I'm not sure it's worth it - it's less than 
the normal fluctuation between test runs. I think a 4 bytes binary size 
will gain much more... but then again, why not do both!
