Does this only work in interactive mode? As soon as I try to
capture it in a function it doesn't work anymore.
def SERIES(s):
R.<x> = QQ[[]]
return s
SERIES(LargeSchroeder)
-1/2*(x + sqrt(x^2 - 6*x + 1) - 1)/x
How do I have to write such a wrapper? Using QQ[[]] is OK for
me, no generality intended.

What people use depends on their background: I guess that someone
who comes from Maple or Mathematica almost automatically writes
'series' and thinks in terms of SR.
