@defproc[(current-future) (or/c #f future?)]{
Returns the descriptor of the future whose thunk execution is the
current continuation. If a future thunk uses @racket[touch], the
future executions can be nested, in which case the descriptor of the
current continuation. If a future thunk itself uses @racket[touch],
future-thunk executions can be nested, in which case the descriptor of the
most immediately executing future is returned. If the current
continuation is not a future-thunk execution, the result is @racket[#f].
