Typescript supports exhaustive switches which are pretty powerful, especially when working with proper union types and the like.

I find using objects mapped as switchKeyToFunction to be more idiomatic and readable. e.g. shapeToDrawFn[shape] But to each their own

Will the compiler check that you have an exhaustive set of keys in your definition of `shapeToDrawFn`? (Not a rhetorical question, I don't know.)
