Fixed a long-standing regression that occurred in version 1.0, which prevented the use of a custom :class:`.MapperOption` that alters the _params of a :class:`.Query` object for a lazy load, since the lazy loader itself would overwrite those parameters. This applies to the "temporal range" example on the wiki. Note however that the :meth:`.Query.populate_existing` method is now required in order to rewrite the mapper options associated with an object already loaded in the identity map. Also, a custom defined :class:`.MapperOption` will now cause lazy loaders related to the target object to use a non-baked query by default unless the :meth:`.MapperOption._generate_cache_key` method is implemented. Fixed bug where the new :meth:`.baked.Result.with_post_criteria` method would not interact with a subquery-eager loader correctly, in that the "post criteria" would not be applied to embedded subquery eager loaders. This is related to 🎫`4128` in that the post criteria feature is now used by the lazy loader. Change-Id: I899808734458e25a023142c2c5bb37cbed869479 Fixes: #4128
