https://bitbucket.org/zzzeek/sqlalchemy/issues/3812/add-raise_on_sql-feature

Michael Bayer:

not sure if we want this.  raise_on_sql means, lazyload if the load means pulling from the identity map or checking for NULL elements in the join condition, otherwise if we are definitely emitting SQL then raise.   POC at https://gerrit.sqlalchemy.org/#/c/203/.   It also includes some changes to the strategy system that should be a good idea, in that we can pass through the strategy_keys to the strategy object itself and allow them to function as options.
