New submission from Sec <[email protected]>:
When trying to extend the builtin bytes class, slices fall back to the builtin
class.
```
class my_bytes(bytes):
def dummy(self):
print("dummy called")
x=my_bytes.fromhex("c0de c0de")
print(x.__class__)
print(x[1:].__class__)
```
x.__class__ returns <class '__main__.my_bytes'> as expected.
But x[1:].__class__ returns <class 'bytes'>
