It doesn't make sense to put a *value* between the <>. You should put
a *type* there. I.e. it doesn't make sense to do
Promise<1> returnOne();
The thing you do is
Promise<integer> returnOne();
'void' is the type for 'nothing', so that's what should be used for
functions that only return undefined. Whether they return that
synchronously or asynchronously.
