New submission from Elazar Gershuni:
The following does not work as expected:
```
from typing import NamedTuple
class A(NamedTuple):
a: int
def __repr__(self):
return 'some A'
def spam(self):
print('spam!')
>>> a = A(5)
>>> repr(a) # should be 'some A'
'A(a=5)'
>>> a.spam()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'A' object has no attribute 'spam'
```
