Hi,
Lets try this again.
Your system could be nice if it really helps rendering speed.
But does it require changes in Django core itself, or is it completely
standalone package that doesn't require changing Django itself to operate?
If it requires changes in Django itself, it would be useful to describe
what changes are needed and why.
Note that you can even no build custom rendering engines since Django
supports those now (with default implementations for Django Templating
Language and Jinja2) your system actually might fall in this category.
Even code is bad you really need to start get some momentum for your
system. Otherwise it's really hard to provide any feedback for example
there might be some edgecases you might not have thought of.
