Consider adding "nout" as in Oc2Py

[PallHaraldsson]

and if, then latest addition here, from 6 days ago:
blink1073/oct2py@8970a66

I'm not sure this applies to Julia, as prety standard to return many there (and I thought in Python?), and in MATLAB:

Removed inferred nout for Octave function calls; it must be explicitly given if not 1. The old behavior was too surprising and relied on internal logic of the CPython interpreter.

I'm just filing so I do not forget, maybe this is not needed, but if a good idea, then also at MATLAB.jl?
