Nope. Here's a stategy to optmize and keep Python's semantics. Compile
each code twice: once with those optimizations, and once without
optimizations. Use the opimized version, until you see a "dangerous"
opcode, such as "import *", "exec", or "eval" -- and then use the
non-optimized version. You can even have the "global"s dictionary
maintain weak references to all of the things it is their globals, and
update them if it is tainted by such an opcode, or a direct manipulation
of its __dict__.
