- """Utilities to enable code objects to be pickled.
-
- Any process that import this module will be able to pickle code objects. This
- includes the func_code attribute of any function. Once unpickled, new
- functions can be built using new.function(code, globals()). Eventually
- we need to automate all of this so that functions themselves can be pickled.
