To be clear, I'm in favour of overflow checks, I just think they in that case should apply in *all* situations, not simply in this one operator. Otherwise Cython will be inconsistent and it makes the language harder to learn. So I'm thinking this: 1) Add integer ** without overflow check 2) Add overflowcheck compiler directive, similar to the nonecheck directive, which checks for overflows in /all/ situations (which defaults to off though) -- Dag Sverre _______________________________________________ Cython-dev mailing list [email protected] http://codespeak.net/mailman/listinfo/cython-dev
