+As we said, comprehensions compiled into functions. That means, we can take a [types.CodeType](https://docs.python.org/3.8/library/types.html#types.CodeType) object for a comprehension, wrap it into [types.FunctionType](https://docs.python.org/3.8/library/types.html#types.FunctionType), and get a function.
+
+```python
+import types
+
+def make():
+    [x*2 for x in _]
+
+code = make.__code__.co_consts[1]
+func = types.FunctionType(code, globals())
+
+# call the function!
+func(iter(range(5)))
+# [0, 2, 4, 6, 8]
+```
