Is your feature request related to a problem? Please describe:
I'm a new KCL users, please correct me if I'm wrong. My understanding is, to use a Python plugin, we need to run a KCL file within Python. This crease inconvenience.

Describe the feature you'd like:
With interpreter-based language, like Python, KCL can run the plug-in on the fly. This would allow KCL to access a rich set of libraries of Python without any boilerplate.

Describe alternatives you've considered:
