initial v1 5 5 sage: S.<x> = W[] 6 6 sage: OL.<pi> = W.extension(x^2  2*a*x + 2) 7 sage: OL(1) >> 1 # should be 07 sage: OL(1) >> 1 8 8 a + pi + pi^3 + a*pi^4 + O(pi^5) 9 9 }}} 10 11 The last answer should be `0`, I guess. 12 13 In any case, results are not coherent: 14 15 {{{ 16 sage: (OL(1) >> 1) >> 1 17 (a^2 + 1) + a*pi + pi^2 + O(pi^4) 18 sage: OL(1) >> 2 19 O(pi^4) 20 }}}
