Generics overload - which one is selected?

[HJarausch]

The following example does not compile due to an `ambiguous call` error.

I don't understand why, since the `T:SomeInteger` version fits better than the 
generic version
    
    
    proc foo[T](A:openArray[T]) =
      echo "Generic version"
      echo A
    
    
    proc foo[T:SomeInteger](A:openArray[T]) =
      echo "SomeInteger version"
      echo A
    
    var
      A = [7,4,6,3,9,1]
    
    foo(A)
    
    
    Run
