Why Jinja is not Django and why Django should have a look at it

1) newforms sometimes takes some serious wrestling to make co-operative

2) The template system bites!

We plan to move to Jinja2 after we finally launch something. However, the biggest blocker for us is lack of auto-escaping.

It shows. Queryset performance is completely divorced from the performance of the template engine as querysets are coded natively in python and just called from the AST evaluator. Also, code generation is incredibly complex (at least compared to an AST evaluator) so unless you convert to something much much faster like machine-code, it's usually not worth the effort (which considering Django's speed relative to other frameworks seems to be the case).

Sorry. Some myths about AST compilers grate at me sometimes.
