    jinja2.optimizer
    ~~~~~~~~~~~~~~~~

    The jinja optimizer is currently trying to constant fold a few expressions
    and modify the AST in place so that it should be easier to evaluate it.

    Because the AST does not contain all the scoping information and the
    compiler has to find that out, we cannot do all the optimizations we
    want.  For example loop unrolling doesn't work because unrolled loops would
    have a different scoping.

    The solution would be a second syntax tree that has the scoping rules stored.
