New description:
#6290 introduced a way to custom-define the latex style of functions, but
it would be great if something similar was made possible for any variable.
I used to do it in the following way, but now I get an error message:
sage: var('hi kunsati delyui')[[BR]]
sage: hi._latex_ = lambda: 'h_i'[[BR]]
sage: kunsati._latex_ = lambda: 'K_{unsat,i}' [[BR]]
sage: delyui._latex_ = lambda: '\delta_{yu,i}'[[BR]]
Traceback (most recent call last):[[BR]]
...[[BR]]
AttributeError: 'sage.symbolic.expression.Expression' object attribute
'_latex_' is read-only[[BR]]

How could the Pynac funtionality of setting latex names for variables at
creation be exposed?
