I find myself using `{[key: string]: mixed}` so much for dynamicish data that I feel like Flow/TypeScript should make it a built-in.

This ends up in most of my projects: type Dict<T> = { [key: string]: T }

Ohhh I like this. I could also just shove it in a typelib if I'm too lazy to import it (which I am).

Just looked at the first project I put that in. Here are the types: export type NumericallyKeyed<T> = { [index: number]: T, }; export type Dict<T> = { [index: string]: T, }; NumericallyKeyed lets you do keyof on an Array without getting method names.
