New issue 3039 by [email protected]: Results of FockStateFermion[Bra,Ket] are system dependent
http://code.google.com/p/sympy/issues/detail?id=3039

from sympy.physics.secondquant import FKet, FBra

FKet([1, 2]) # gives
-FockStateFermionKet((2, 1)) or
FockStateFermionKet((1, 2))

FBra([1, 2]) # gives
-FockStateFermionBra((2, 1)) or
FockStateFermionBra((1, 2))

(I thought I had made this report but didn't find it. I know things in the physics module are in flux, but this is something that might be addressed, too.)
