Dear Cells Users:

Maybe you have come across this also ...

While working on the other challenges I have been telling on this  
list I am also trying to set-up an authorization model for Cells.

I need to check permissions to Create, Update, Read, and Delete a  
cell slot. I thought about having hooks on each of these operations  
such that on every such operation within Cells an "outside function"  
can be called. These just return t or nil depending on permission  
check success or failure. As the model outside can be quite different  
from case to case (app to app) I did not think about implementing  
this within Cells.

So

(cells:add-hook 'cells:slot-read slot-reference 'my-permission-check- 
function)

would install that hook.

Or should I keep this on class level instead of on slot level because  
of possible impacts on propagation speed and other inner Cells  
aspects? I'd prefer to get the fine-grained control here and no, I'm  
not trying to get into the premature optimization game but want to  
get some basic thoughts straight.

Again: Any feedback very welcome!

Cheers,
     Frank
