[New-bugs-announce] [issue35115] UUID objects can't be casted by `hex()`

[fcurella]

New submission from fcurella <flavio.curella at gmail.com>:

Casting a UUID to an `int` or to a string works as expected:

```
import uuid

value = uuid.UUID()
str(value)
int(value)
```

but casting to an `hex()` raises an exception:

```
import uuid

value = uuid.UUID()

# uuid instances already have the correct value stored in the `.hex` attribute
value.hex

# this raises `TypeError: 'UUID' object cannot be interpreted as an integer`
hex(value)

# this behaves correctly
hex(value.int)

```

Adding support for `hex()` should be simple enough as adding the following to the UUID class in https://github.com/python/cpython/blob/54752533b2ed1c898ffe5ec2e795c6910ee46a39/Lib/uuid.py#L69:

```
def __index__(self):
    return self.int
```
