Out of curiosity, I was testing further @gramm and came across an infinite recursion at the highlighted lines:
https://github.com/piermorel/gramm/blob/master/%40gramm/gramm.m#L180
https://github.com/piermorel/gramm/blob/master/%40gramm/set_names.m#L29

To reproduce it, use the following class:

classdef recurse
  properties
    value = [];
  endproperties
  methods
    function obj = recurse ()
      obj(1).value.prop = 42;
    endfunction
  endmethods
endclassdef

Calling the constructor returns:

octave:1> recurse
error: max_recursion_depth exceeded
error: called from
    recurse at line 7 column 25

This disappears if obj.value is used instead of obj(1).value.
