Python 3 has deprecated formatargspec and requested that Signature be used instead, however this requires a full reimplementation of formatargspec() in terms of creating Parameter objects and such. Instead of introducing all the object-creation overhead and having to reinvent from scratch, just copy their compatibility routine. Utimately we would need to rewrite our "decorator" routine completely which is not really worth it right now, until all Python 2.x support is dropped. cs7|}|kr3|d|7}n|S(Ns: ((R tresult(R Rqt formatarg(sI/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/util/compat.pytformatargandannotation-s  Rrt(s, t)treturnN(R]RdtappendRtjoin(RRRRRR R Rvt formatvarargst formatvarkwt formatvaluet formatreturnsRqRwtspecst firstdefaulttiR tspect kwonlyargRu((R RqRvsI/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/util/compat.pytinspect_formatargspecs2      (t formatargspeccOst|dd!|S(Nii(t_inspect_formatargspec(Rtkw((sI/opt/alt/python27/lib64/python2.7/site-packages/sqlalchemy/util/compat.pyRUscgsg}g}d}zcyIx=|D]5}|j}|j}|j||j|qW|VWntj}nXWdxE|r|j}y||rd}nWq{tj}q{Xq{W|dkrt|d|d|dnXdS(sImplement contextlib.nested, mostly for unit tests.
