Is hilarious mistake in Python design. Thanks @elfprince13.

```python
def x():
e = None
while e is None:
try: print(input("? "))
except Exception as e: print(repr(e))

x()
```

Result:
```
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 3, in x
UnboundLocalError: local variable 'e' referenced before assignment
```

@AccordionGuy the formatting in that post looks broken to you too, right? It's not only broken on my instance but in the actual post? Haven't yet figured out how to view the JSON-LD source.
