Na, na, na, I win.
But that's peanuts.
I can make an application running 100 times slower just
by replacing 'z' with Dutch characters. [*]. I win again.
I can take the same application and replace 'z' by ..., and
... No, I do not win :-( . Python fails.
[*] Unicode is fascinating, working with it is a little
