Review comment:
There are already two `from sqlalchemy import ...` statements: the first
imports types, the second imports (SQL) expressions.
I can introduce a third one.
Or combine all into one like this (lexicographically sorted):
```
from sqlalchemy import (
Boolean, Column, DateTime, Float, ForeignKey, ForeignKeyConstraint,
Index,
Integer, LargeBinary, PickleType, String, Text, UniqueConstraint,
and_, asc, func, or_, true as sqltrue
)
```
