How can I "look" at a (e.g. linear) form? (e.g. with form.x_repr_latex_)

Hello everyone,

After defining a form in (the python version) of fenics, is there any way to "look" at it later on?

So I want something similar to the following:

u = TrialFunction(function_space)
v = TestFunction(function_space)
form = inner(grad(u), grad(v))*dx
...
...
form.x_repr_latex_()

e.g. in order to make sure within the interactive python shell that I am using the right form or output the latex (or any human-readable) representation for documentation purposes.

But the above example returns an error message:

In [4]: error_form.x_repr_latex_()

    423     argument_names = formdata.argument_names
    424     coefficient_names = formdata.coefficient_names

AttributeError: 'FormData' object has no attribute 'name'

I am still quite new to python, but looking at (my Version of) the source code it really seems that all three of the above attributes are not set within the compute_form_data() function. Is this a bug or do I just need to compute the form differently? Having a latex representation would be my first choice but as mentioned, I could settle for any Human-readable representation.
