Details:

There seems to be a regression with subsasgn in the context of array of
objects and chained assignments. The following code works in 5.2 but returns
the error below with dev:


classdef foo
  properties
    a;
  endproperties
  methods
    function obj = foo
      obj.a = struct ("b", 1);
    endfunction
  endmethods
endclassdef



obj(1) = foo;
obj(2) = foo;
obj(1).a.b
  ans = 1
obj(1).a.b = 2
  error: invalid dot name structure assignment because the structure array is
empty.  Specify a subscript on the structure array to resolve.
