>>> timeit.repeat("(x*1000 + y)[:-1]", setup="x = 'abc'; y = 'z'")
[1.4027834829454946, 1.38714224331963, 1.3822586635296261]
>>> timeit.repeat("(x*1000 + y)[:-1]", setup="x = 'abc'; y = '\u0fce'")

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
bit travelling.
