In our code, we have a closed interface type with many variants, not unlike an AST. We frequently add new variants to that interface. It is nice to have a tool tell us which parts of the code need updating to account for the new variant. This tool does that. It trivially reduces bugs and saves development time.

If you think people like me "don't get stuff done," then please, take a stroll through my Github. ;-)
