Comment #6 on issue 2610 by vlada.pe...@gmail.com: Wavefunction documentation errors under Python 3
http://code.google.com/p/sympy/issues/detail?id=2610

I actually don't get it with -Qnew, but if you do then that's good enough. Tomo, are you sure you gave the right expression here? That evaluates to sqrt(2) (in SymPy and on paper). I guess it has something to do with it also being a Wavefunction, but I don't know anything about that. Anyway, I've tested some more and perhaps it's caused by this:

# Python 3
L = 1
sqrt(2)
2**(1/2)
sqrt(2/L)
1.41421356237310

In Python 2 both are 2**(1/2). This feels like a real and important bug to me.
