Module support?

It's quite simple.  If you have to use HMVC to solve whatever problem you are trying to.  Then you just don't know how to design and develop an application.

My answer is no.  There is no need for HMVC.  I have an enterprise application.  It's actually 4 distinct applications built with 1 common middle-ware.  I looked at HMVC in the beginning and laughed.  There was no need.  Actually, it would have complicated things.

Are you high?  A controller which then would hit a model and view and then hit another controller elsewhere?  Yeah, kinda smells like you don't know how to code.

nice speech!

i use it anyway because of the fact of the clean encapsulation
In our own B2B shop solution without being able to create widgets (modules) we would suffer to much

i think its mandatory for a future version of CI to implement this as a built-in feature

and no i'm not high
