On Linuxyou can also open("/proc/self/mem", "w").I don't think that people get their hands on frame objects by pure chance,but the possibility exists. Moreover, conditionally allowing changes tof_lasti is limiting and complex because of the stack and block stack. Forsafety I'd consider writing the frame-object-modifying code in a Cextension module, carefully documented as "don't use this". Armin
