You have several options, e.g., define a
colv(v::AbstractVector) = reshape(v, length(v), 1)
function. Or you can define a comparison function,
cmpcolv(v1, v2)
which will do the comparison with what you receive from SymPy, accepting
either AbstractVector or AbstractMatrix arguments.

Hi,
It looks like in 5cf9dbba8d350b4c0df179c7d983d5933c7d2119 the `sum` method

I was thinking of starting up a Julia NLP meta-project on github if there's
enough interest. It could host projects like textanalysis.jl, a Julia
interface to NLTK, a Julia interface to some of Stanford's NLP tools, and
whatever more native solutions people put together.

JuliaText would be great.
TextAnalysis.jl really needs a lot of love to move forward. For now, I’d
strongly push people towards NLTK.

Agree.
People with programming background won't expect x and x + 0 (x * 1, x ^ 1,
etc) to be the same thing. (They are equal, but definitely not the same
copy). Even in MATLAB or Python/Numpy, when you modify y = x + 0, the
values in x are not affected.
