with the debugger i found out that the char ':' turns into a magic-colon when builtin('subsref',self,s) is called. Can i avoid that somehow?

Hi

the following example fails on the strcmp line with:
error: invalid use of colon in function argument list

It doesn't fail without the subsref definition.
Any idea for a workaround?

a = Value([1,2,3,4,5])
a.get(':')

classdef Value < handle
  properties
    value
  end
  methods
    function self = Value(val)
      self.value = val;
    end
    function varargout = subsref(self,s)
      [varargout{1:nargout}] = builtin('subsref',self,s);
    end
    function r = get(self,varargin)
      if strcmp(varargin{1},':')
        disp('hello');
      end
      r = self.value(varargin{1});
    end
  end
end
