Isn't it already easy enough to do that today?
>>> import base64; exec
... Hello, world!
Admittedly, you could look for anything like that and be suspicious, but
running a program from an untrusted source is always going to be
dangerous. For standalone applications, you can already do things like
compile malicious C extension modules that are impossible to verify.
As for programs that use Python for scripting, shouldn't it be up to
them to ensure that it runs in a restricted environment? A browser, for
instance, would have to do that already.
