> *Background:*
> Having no runtime extension should be a convenience feature only, one could both use the python code itself.
> It should be possible to access {{{color:#403294}{{sys.path}}{color}}} from the cpp wrapper like this: [https://pybind11.readthedocs.io/en/stable/advanced/embedding.html#importing-modules]
> !Screenshot 2020-05-13 at 16.49.35.png|width=631,height=142!
> Having this code called before the script-engines start causes crash even under gil.
> *Proposal:*
> Extend the python script engine with an interface that handles module imports and call to it before any {{{color:#403294}{{eval}}{color}}} call happens.
