Comment:
What exactly is the problem?
It is
{{{
sage: S = SymmetricFunctions(ZZ)
sage: S.inject_shorthands()
doctest:...: RuntimeWarning: redefining global value `e`
doctest:...: RuntimeWarning: redefining global value `m`
sage: s[1] + e[2] * p[1,1] + 2*h[3] + m[2,1]
s[1] - 2*s[1, 1, 1] + s[1, 1, 1, 1] + s[2, 1] + 2*s[2, 1, 1] +
s[2, 2] + 2*s[3] + s[3, 1]
}}}
The last line fails with an error when doctesting, but works fine when
doing the same in an interactive session.
