iterate_props yields Property instances; maybe p.key is the name u
want.
here a generic wrapper simulating dict.items():
def props_iter( mapr, klas =sqlalchemy.orm.PropertyLoader ):
try: i = mapr.properties
except: # about r3740
for p in mapr.iterate_properties:
if isinstance( p, klas):
yield p.key, p
else:
for k,p in i.iteritems():
yield k,p
