Same here :)

I'm thinking we might *almost* have enough functionality in @pyobj that
you could try to use that directly in Symbolic's python_ipc_pytave.m:

After the line `pyexec(s)`, the stuff we want to return to Octave is in
a Python list called `_outs`.  Maybe we can just use something like:

tmp = pyeval('_outs[0]');

(note currently pyobj will not deal with the list correctly itself,
you'll need to get the elements of the list).

See python_header.py: "octoutput" function, specifically after the line
`elif x is None or isinstance(x, (sp.Basic, sp.MatrixBase)):`.  Compare
this to `extractblock.m` so see which properties of a SymPy Python
object we need to make a @sym object.
