Previously this printed 1 and 2:

function myfunc
   local(1); % local is a function
   local = 2; 
   disp(local);
end

function local(x)
   disp(x)
end

This now errors:

function myfunc
   % local is an undefined variable
   local(1); % Errors
   local = 2; 
   disp(local);
end

function local(x)
   disp(x)
end
