It's better, the majority of these changes look more readable to me.
also found some docstrings that had formatting / quoting issues.

Building on newly robust lambdas in
I29a513c98917b1d503abfdd61e6b6e8800851aa8,
convert key loading off of the "baked" system so that baked
is no longer used by the ORM.

in order to accommodate relationship loaders
with lambda caching, a lot more is needed. This is
a full refactor of the lambda system such that it
now has two levels of caching; the first level caches what
can be known from the __code__ element, then the next level
of caching is against the lambda itself and the contents
of __closure__. This allows for the elements inside
the lambdas, like columns and entities, to change and
then be part of the cache key. Lazy/selectinloads' use of
baked queries had to add distinct cache key elements,
which was attempted here but overall things needed to be
more robust than that.
This commit is broken out from the very long and sprawling
commit at Id6b5c03b1ce9ddb7b280f66792212a0ef0a1c541 .

The coercions system allows us to add in lambdas as arguments
to Core and ORM elements without changing them at all. By allowing
the lambda to produce a deterministic cache key where we can also
cheat and yank out literal parameters means we can move towards
having 90% of "baked" functionality in a clearer way right in
Core / ORM.
As a second step, we can have whole statements inside the lambda,
and can then add generation with __add__(), so then we have
100% of "baked" functionality with full support of ad-hoc
literal values.
Adds some more short_selects tests for the moment for comparison.
Other tweaks inside cache key generation as we're trying to
approach a certain level of performance such that we can
remove the use of "baked" from the loader strategies.
As we have not yet closed #4639, however the caching feature
has been fully integrated as of
b0cfa7379cf8513a821a3dbe3028c4965d9f85bd, we will also
add complete caching documentation here and close that issue
as well.
Closes: #4639
Fixes: #5380
