Comment (by Han Frederic):
Hi all, I am starting the comments, there something curious I remember,
one coercion is much slowler than the other one (it is not the case in
pure python).
{{{
from sage.libs.giac import *
a=libgiac(2)
sage: time l=[ a+1 for i in range(10**5)]
CPU times: user 0.20 s, sys: 0.00 s, total: 0.20 s
Wall time: 0.19 s
sage: time l=[ 1+a for i in range(10**5)]
CPU times: user 1.04 s, sys: 0.00 s, total: 1.04 s
Wall time: 1.03 s
}}}
any idea?
