That would be good - it looks interesting.   It's a shame that
it's Mac specific though :-(

There's no reason why you can't byte-compile something so that it's
not interpreted.  e.g.:

>>> code = compile('n + 1', '', 'single')
>>> code
<code object ? at 0xb7eb49e0, file "", line 1>
>>> def add1(n):
...     exec code
>>> add1(2)
>>> add1
<function add1 at 0xb7eb7f44>
>>> n
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
NameError: name 'n' is not defined
