Presumably the standard version of Future would provide some convenient way
to get the symbol.  The library would use that to conditionally provide the
symbol-named alias.  Something along these lines:

    if (typeof Future !== "undefined")
        MyPromise.prototype[Future.thenSymbol] = MyPromise.prototype.then;
