[go-nuts] Are short variable declarations necessary?

[T L]

alternative question, why followings are not accepted in syntax:

    if var x = 5; x > 3 {
        _ = x
    }

    for var x = range []int{0,1,2} {
        _ = x
        
    }

    switch var x = "abc"; x {
    default:
        _ = x
    }
    
    switch var x = (interface{}(true)).(type) {
    default:
        _ = x
    }
