This problem is probably realted:

In x.sage, type:

print(__name__)

In sage 10.7, sage x.sage prints sage.all. But in sage 10.5, sage x.sage prints __main__.

In sage 10.7, sage x.sage prints sage.all. But in sage 10.5, sage x.sage prints __main__.

I came here to report this. This effectively breaks scripts that gatekeep execution by if __name__ == "__main__"
