What are you using LibCST for?

Reading about all the different use cases helps keep me motivated, and we might learn from each other.

Mainly to improve FastAPI ecosystem.

This week we merged Kludex/starlette#1376 on Starlette, and I'm creating a codemod to make our users' life easier.

Libcst is used in the micropython-stubber project to merge different partial stub definitions to create stub packages that are published to pypi, and to generate different variations of stub generation scripts that are run on micropython microcontrollers.
