Developer notes

• sqlalchemy checks kwarg consumption in DefaultEngineStrategy.create
  • wrapped objects must have the same signature with internal
  • To create method with a specific signature, we have to eval ref
  • checks __init__ of Dialect, DBAPI, Pool and Engine.
• Dialect.dbapi is not explained in the doc as interface. but
  • db.engine_create defaults to use DefaultEngineStrategy.create
    • DBAPI callable passed in module parameter
    • or Dialect.dbapi callable
