I would not object to removing it "static" as a reserved keyword, but
I checked, and there are some .m files in Octave Forge that are still
using it.  So before removing it completely, we should probably warn
that it is deprecated for a few releases first.

Although set and get are normally function names, they are also
recognized specially for some kind of classdef syntax.  They are not
keywords in Matlab though, so we could probably also fix Octave to
handle this syntax without requiring actual reserved keywords.
