How about you can add the path of these functions in your global /
user-specific '.octaverc' file? You can also set dispatch() to them,
if Im not wrong, or set something like:

address@hidden
address@hidden

Also, I'd really think people from Signal-Processing field would want
comb() to be a comb-filter instead! Anyway, its just that we cant 
probably have a system-wide implementation of this idea.

Also 24! would make Octave incompatible at a grammar level, with the
Matlab language. I also dont see any advantages to doing that, other
than syntactic sugar.

Maybe when someone writes a lisp-MACRO like interface to Octave, the
we could all have our own mini-languages within Octave, and still speak
grammatical Octave!
