// Instead of using any - or another less-than-ideal type - to workaround a
// TypeScript problem or bug, create a type alias and use that instead.
// Wherever possible, use a TypeScript issue number in the type - something
// like TS_18757 - or use a descriptive name and leave a detailed comment
// alongside the type alias.
