What I mean is creating a new class by extending a builtin type. Like:

@foo/foo.m
function f = foo(p)
    p = double(p);
    f.meta = struct();
    f = class(f,"foo",p);
endfunction

Then class foo would behave just like a double array/matrix except for
methods that explicitly add or override that behavior. So in that
example, @foo would just inherit all the functions that already would
be called if the first argument was a double. You could use that to
create a matrix that used degrees instead of radians for trig
functions, for example.
