Comment(by malb):
The only issue I can see is the potential performance overhead.
Vanilla 4.2.1:
{{{
sage: P.<x> = GF(2)[]
sage: f = P.random_element(50)
sage: %timeit f<<50
1000000 loops, best of 3: 792 ns per loop
}}}
This patch:
{{{
sage: P.<x> = GF(2)[]
sage: f = P.random_element(50)
sage: %timeit f<<50
1000000 loops, best of 3: 952 ns per loop
}}}
Maybe a cdef method could be added which everyone ({{{shift}}},
{{{__lshift__}}}, {{{__rshift__}}}) calls?
