Since Expression is a cython class, you cannot overwrite the _latex_()
method.
Pynac supports setting latex names for variables at creation, but this
functionality is not exposed in the wrapper. Another solution by
hacking latex_variable_name() might be possible, but I would like to
avoid that if possible.
Feel free to open a new issue in trac about it.
