Sequtil Question

Hello, the following code doesnt compile. Is it a bug? Or am i doin sth wrong?
    
    
    import future
    (lc[i | (i<-0..9), int]).filterIt(it < 3).echo;
    
    
    Run

On the other hand this does compile :O
    
    
    @[1,2,3,4,5,6].cycle(2).filterIt(it < 5).cycle(2).filterIt(it > 1).echo
    
    
    Run

Thanks :)
