Comment:

 I'm ready to give this a positive review, but now (Sage 4.6.2) I'm getting
 a failing doctest with `latex` on a coproduct (note the missing `1` at the
 end of the latex string):

 {{{
 sage: A7 = SteenrodAlgebra(7)
 sage: c = Sq(2).change_basis('adem').coproduct()
 sage: c
 1 # Sq^2 + Sq^1 # Sq^1 + Sq^2 # 1
 sage: latex(c)
 1 \otimes \text{Sq}^{2} + \text{Sq}^{1} \otimes \text{Sq}^{1} +
 \text{Sq}^{2} \otimes
 }}}

 This is probably related to bugs in the code for tensor products of
 algebras, but I haven't been able to track down the precise problem.
