Better description: If a field of a class has a synonym and the class also has a group of deferred columns, trying to access the deferred group results in an error complaining that the SynonymProperty has no attribute 'strategy'

Sorry that I used elixir to demonstrate, but I am new to SQLAlchemy and it appears in the SA part of the code and not the elixir layer. (Please don't whip me if I'm wrong I'll buy you a beer at pycon instead.)

(original author: ged) I'll look into this to see if the problem is ELixir-specific or not, and will produce an SQLAlchemy-only test case if it's not.

(original author: ged) My tests seem to show it's really an Elixir issue since I can't seem to reproduce the problem with an SA-only code. Closing here for now.
