Nitpick:

 >>> class Err(Exception): pass
...
 >>> def it():
...     raise Err()
...     yield 42
...
 >>> min(it())
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "<stdin>", line 2, in it
__main__.Err
 >>> min2(it())
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "<stdin>", line 5, in min2
   File "<stdin>", line 2, in it
__main__.Err
 >>> min2(it(), default=12)
12

Shouldn't the last one raise Err as well?
