IfAvailable<T, Fallback>:(boolean) extends (T extends never ? true : false) ? Fallback : keyof T extends never ? Fallback : T
If the lib "ES2015.Collection" is not included in tsconfig.json,
types like ReadonlyArray, WeakMap etc. fall back to any (specified nowhere)
or {} (from the node types), in both cases entering an infinite recursion in
pattern matching type mappings
This type can be used to cast these types to void in these cases.
