I skimmed the bug report comments but didn't find an answer to this: Why not just monkey-patch? When a module function calls on a support function and you want to change that support function's behaviour, isn't monkey-patching the most usual? Several possibilities come to mind, but without knowledge of internals, I have no idea what's actually the case. * Patching builtins is too confusing or dangerous, and should be avoided? * You want to narrow the scope of the patch rather than do it globally? * Explicit is better than implicit? It just strikes me as something where an API change may not be necessary. ChrisA -- http://mail.python.org/mailman/listinfo/python-list
