Changeset:   ae4629e6a0ff
Branch:      None
User:        zzzeek
Date:        2013-11-23 23:03:48
Summary:     - Some refinements to the :class:`.AliasedClass` construct with regards
to descriptors, like hybrids, synonyms, composites, user-defined
descriptors, etc.  The attribute
adaptation which goes on has been made more robust, such that if a descriptor
returns another instrumented attribute, rather than a compound SQL
expression element, the operation will still proceed.
Addtionally, the "adapted" operator will retain its class; previously,
a change in class from ``InstrumentedAttribute`` to ``QueryableAttribute``
(a superclass) would interact with Python's operator system such that
an expression like ``aliased(MyClass.x) > MyClass.x`` would reverse itself
to read ``myclass.x < myclass_1.x``.   The adapted attribute will also
refer to the new :class:`.AliasedClass` as its parent which was not
always the case before. [ticket:2872]
