 Replacing the kind of awkward stack function is one of those long-term
 projects with a ticket on the feature tracker on sourceforge. It is
 tedious, however, that's why I haven't found the time to finish it.
 Maybe you have the motivation to work on a package like that. 
Thanks for your reply, Sven. I actually worked on it:
https://github.com/atecon/stack
The public function is called stack_data() and the sample script 
illustrates its usage. Stuff is tested and seems to work fine. What do 
you think about it?
