Does Eval Module work Now?

I agree Lua makes it a lot flexible and the cost of Lua is rather small. To achieve rewrite  I am using content_by_lua once the rewrite is complete, I just do ngx.exec to other locations. Gives me in effect as eval module.

On auth side, at present I use ngx_auth_request and use content_by_lua to serve the request. So yes, that will be very useful.

Personally I'd recommend ngx_lua too, it's much more stable than (my
fork of) ngx_eval :)

Actually I'm implementing the "rewrite_by_lua" directive for ngx_lua
(see its "rewrite" branch on GitHub), which can trivially do all the
tasks originally done by ngx_eval :)

And there will also be a "access_by_lua" directive too. Such that many
tasks done by ngx_auth_request can also be trivially achieved, and
with amazingly more flexibility ;)
