I would propose that one. Because you have a dict of the already known
variables anyways I would traverse the AST. The AST however changed
from Jinja 1.0 to 1.2 so you would have to required the most recent
version. The current AST is final and interfaced by at least one
application, albeit undocumented.
If you call ``jinja_environment.parse('template sourcecode')``
you get back a `Template` node which you can then traverse for the
`NameExpression` nodes which represent variable names. The only thing
you have to make sure it to exclude name nodes returned that are in fact
assignments to those nodes.

Done, didn't know that the list was open ^^
