You can also find the following trick convenient:

options.parameter_name = "IDontLikeCamelCasing"; % default value
% ...etc
for i = first_param_name:2:nargs
  options.(varargin{i}) = varargin{i+1};
endfor

now to query for option option1 you do `options.option1'. Handling map
in a DLD function is also simple.
