A plea for int overflow checking as the default

Hello, I have a small problem with SaferIntegers, still using the same code:

 function collatz(lim)
    max=1
    for i in 1:lim
      c=0
      n=SafeUInt64(i)
      while n!=1
        if n&1==0 n>>=1
        else      n=3*n+1
        end
        c+=1
      end
      if c>max
        max=c
        println("at $i new max=$max")
      end
    end
  end

  collatz(1000)

 ERROR: MethodError: >>(::SaferIntegers.SafeUInt64, ::Int64) is ambiguous. Candidates:
