Help writing a timeout macro

Thanks for this useful snippet.

I wanted something very similar but with the possibility of a default value in case of failure. So I came up with this:

macro timeout(seconds, expr, fail)
    quote
        tsk = @task $expr
        schedule(tsk)
        Timer($seconds) do timer
            istaskdone(tsk) || Base.throwto(tsk, InterruptException())
        end
        try
            fetch(tsk)
        catch _
            $fail
        end
    end
end

x = @timeout 1 begin
    sleep(1.1)
    println("done")
    1
end "failed"
