Raised StopIteration on insert

[sdrenn]

When I execute code like this

engine = create_engine(db_opt)
Session = sessionmaker(bind=engine)
session = Session()
item = Item(data='test')
session.add(item)
session.flush()

the following error appears:

RuntimeError: generator raised StopIteration

I'm using Python 3.7. On 3.6 it works fine.
Looks like it's because of how Python 3.7 handles StopIteration:

Fixed in version 0.0.8.

It looks like the issue is still here with version 0.0.10 and Python 3.7.3.

@a-rodin please provide some example to reproduce this error.

@xzkostyan I actually encounter the error when I use clickhouse-sqlalchemy with IPython SQL magic. When I try run magic like

%%sql
drop table if exists my_table_to_drop;

then it works fine on Python 3.6 (no results returned) and raises a StopIteration error on Python 3.7.

It believe that it is not an issue of of IPython SQL magic, because the similar query works fine with SQLite and Python 3.7.
