careful: when you get as far as executing the "def" statement, the 
function body has already been compiled.  the byte code for the function 
is stored as a module-level constant:

 >>> code = compile("def func(arg): print arg", "", "exec")
 >>> dis.dis(code)
   1           0 LOAD_CONST               0 (<code object func ...>)
               3 MAKE_FUNCTION            0
               6 STORE_NAME               0 (func)
...
