I talked to the team in charge of google-cloud-storage python library. They
mentioned that they have put all the feature requests on the batch module on
hold since there is a new API for batch operation under development in GCS.
This is both good news and bad news for us. On one hand, this means that for
a little while we won't see any changes in this module so the way we
referencing the private member variable will still work. On the other, when the
new API is ready, it is very likely to introduce breaking changes.
I have already informed them to let us know when it happens, but at this
moment, we don't have any action item.
Notice that, an alternative to get rid of referencing the private member
variable is to do a hack as follows:
```
responses = None
current_batch = self.client.batch(raise_exception=False)
with current_batch:
# call and put batch operations in queue
# ...
# call finish to get the responses
responses = current_batch.finish(raise_exception=False)
# throw a blank exception so finish() will not be triggered when exiting
the with statement.
raise Exception("nothing wrong, just exiting with w/o calling finish()")
```
I don't think we will go with this hack given the incoming change on the
batch module.
