*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]

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.
