Is it possible to mimic Go's Goroutines

[dom96]

Yes, it is possible:
    
    
    import asyncdispatch
    
    proc A() {.async.} =
        for _ in 1..10:
            echo("A")
            await sleepAsync(0)
    
    proc B() {.async.} =
        for _ in 1..10:
            echo("B")
            await sleepAsync(0)
    
    asyncCheck A()
    waitFor B()
    
    
    Run
