Are functional objects (functors/closures) possible?

To me, that seems to be a reasonable way to solve this problem.  If
many global variables bother you, you can pack all the data in a
structure or cell array (in recent snapshot versions of Octave, at
least).

Right, Octave does not support this.

Sorry, I'm not following what you want.  Can you be more specific
about what it is you want and how it would help you?
