This is pretty annoying change.

If you have any .rb files under a view path, AP is going to try to precompile them.

Just put a module under app/views echo "module Foo; end" > app/views/foo.rb and your app will just crash will an error message saying "module definition in method body".

My personal usage is mustache view classes.

@josh I added this since @dhh asked for it after of see it in Railscasts, I will talk with him on CF to check if we can found any solution or if we should revert this


I like that jbuilder (and similar extensions) use its own extension, not .rb.

We'll just go with .ruby for now, then.
