Comment (by kalvotom):
After some more digging it turned out the this is almost OK in the most
recent git version of Sympy (not 0.7.6 which is shipped with Sage). Class
Function
[https://github.com/sympy/sympy/blob/master/sympy/core/function.py#L679
has a _sage_ method] and hypergeometric function `hyper` is also
[https://github.com/sympy/sympy/blob/master/sympy/functions/special/hyper.py#L306
correctly dealt with].
However, the example mentioned above still fails because Sage does not
know `exp_polar` function. I have created
[https://github.com/sympy/sympy/pull/9224 this pull request] which adds
`_sage_` method to `exp_polar` and returns the usual exponential.
