Hey all, thanks for the amazing work you all doing! 🙇

Description of the false positive
I am working on an open source reactjs project and I am also using flowjs to type-check. Sometimes to annotate in flowjs you can state that a value will be of type of a class. LGTM in this case would not catch this annotation and will report that the imported class is unused.

URL to the alert on the project page on LGTM.com
