Re: [pypy-dev] [pypy-commit] pypy default: Unroll list.count() when the list is virtual or very small and constant lenght

Hi Alex,

please revert this change, it can lead to combinatorial explosion: it can give a bridge per pattern of where in the list the object is found.

Doesn't list.count() traverse all the list in all cases? -- Amaury Forgeot d'Arc
