Re: High performance with stateful TemplateDirectiveModel

Hi Daniel!

Interesting and useful. I'll check it out as soon as I get some time for 
it.

I'm not sure I can use the isNestedOutputCachable() feature since some 
of the content that I want to cache may contain things that are using 
dynamic expressions (like including a constant that is environment 
specific).

Still the whole new feature is interesting.

Thanks!
