For the first point: cell() is already a builtin function, so you have to

emulate a method call on a dataframe object, this is the purpose of
x.cell(some_range).

I'm not sure I understand what you are saying. Classes can overload builtin functions. For example, create a directory called @foo and the following files:

@foo/foo.m:

function foo = foo()

  foo.data = 1 ;

  foo = class(foo, "foo") ;

endfunction

@foo/cell.m:

function cell(foo)

  "Hello, world!"

endfunction

Then in octave this is what happens:

octave:1> f = foo 

f = <class foo>

octave:2> cell(f)

ans = Hello, world!
