Replying to [comment:13 ncohen]:
> Okayyyyyyyy.. This being said, why did you change the bint to int ?
The exception is propagated with the return value `-1`, I think it is
cleaner to make it an int.
Anyway, the choice `int/bint` is just a compiler instruction for Cython.
There is no gain of having it a `bint` type here since it is always used
in C code. The purpose of the bint type is to mix well Python booleans
with C ints. One difference (that I learn few seconds ago) is in
{{{
def f(b):
int x = b
bint y = b
}}}
The first conversion will involves `b.__int__` while the second
`b.__nonzero__`.
