Details:

This was reported on irc with the MIRToolbox
(https://www.jyu.fi/hum/laitokset/musiikki/en/research/coe/materials/mirtoolbox/Download).

The following minimal reproducer throws the error for me:


#### myplot.m ####

function myplot (ax)
  if (isempty (ax))
    figure ();
  endif

  plot (1:10);
  hold on
  axis tight
endfunction

#### @myclass/myclass.m ####

function y = myclass ()
  y = class (struct (), "myclass");
endfunction

#### @myclass/plot.m ####

function plot (x)
  axis = [];
  myplot (axis);
endfunction



The error is the same as if "axis" were a variable in the current scope, it
appears as a "parser error" on the function that is called with command
syntax.


parse error near line 8 of file /path/to/myplot.m

  syntax error

>>>   axis tight
                ^

error: called from
    plot at line 3 column 3
