Comment (by nthiery):
Replying to [comment:7 jdemeyer]:
> Why not remove `_check_trac_number(trac_number)` altogether? Perhaps
convert the number to `int()` or use `__index__()`, which will throw an
exception if needed.
Ah, thanks for the pointer to __index__! That's exactly what I was
looking for. In a first version, I was using int(), but then "10963"
was accepted.
I left {{{_check_trac_number}}} though, since someone had taken the
time to write a nice error message, and a .__index__ AttributeError is
not super informative in this case.
Oh, big improvement: now the number must be bigger than 1 :-)
Cheers,
Nicolas
